Predict/Calculate In Problem 57, suppose the Jet Ski is moving at a speed of 11 m/s relative to the water. (a) At what angle must you point the Jet Ski if your velocity relative to the ground is to be perpendicular to the shore of the river? (b) If you increase the speed of the Jet Ski relative to the water, does the angle in part (a) increase, decrease, or stay the same? Explain. (c) Calculate the new angle if you increase the Jet Ski speed to 15 m/s. (Note: Angles are measured relative to the x axis shown in Example 3-11 )

- A truck loaded with cannonball watermelons stops suddenly to avoid running over the edge of a washed-out bridge (Fig. P3.48). The quick stop causes a number of melons to fly off the truck. One melon leaves the hood of the truck with an initial speed vi = 10.0 m/s in the horizontal direction. A cross section of the bank has the shape of the bottom half of a parabola, with its vertex at the initial location of the projected watermelon and with the equation y2 = 16x, where x and y are measured in meters. What are the x and y coordinates of the melon when it splatters on the bank?arrow_forwardOne strategy in a snowball fight is to throw a snowball at a high angle over level ground. Then, while your opponent is watching that snowball, you throw a second one at a low angle timed to arrive before or at the same time as the first one. Assume both snowballs are thrown with a speed of 25.0 m/s. The first is thrown at an angle of 70.0 with respect to the horizontal. (a) At what angle should the second snowball be thrown to arrive at the same point as the first? (b) How many seconds later should the second snowball be thrown after the first for both to arrive at the same time?arrow_forwardYou can use any coordinate system you like to solve a projectile motion problem. To demonstrate the truth of this statement, consider a ball thrown off the top of a building with a velocity v at an angle with respect to the horizontal. Let the building be 50.0 m tall, the initial horizontal velocity be 9.00 m/s, and the initial vertical velocity be 12.0 m/s. Choose your coordinates such that the positive y-axis is upward, the x-axis is to the right, and the origin is at the point where the ball is released, (a) With these choices, find the balls maximum height above the ground and the time it takes to reach the maximum height. (b) Repeat your calculations choosing the origin at the base of the building.arrow_forward
- Review. You are standing on the ground at the origin of a coordinate system. An airplane flies over you with constant velocity parallel to the x axis and at a fixed height of 7.60 103 m. At time t = 0, the airplane is directly above you so that the vector leading from you to it is P0=7.60103m. At t = 30.0 s, the position vector leading from you to the airplane is P30=(8.04103i+7.60103j)m as suggested in Figure P3.31. Determine the magnitude and orientation of the airplanes position vector at t = 45.0 s. Figure P3.31arrow_forwardA helicopter blade spins at exactly 100 revolutions per minute. Its tip is 5.00 m from the center of rotation. (a) Calculate the average speed of the blade tip in the helicopter's frame of reference. (b) What is its average velocity over one revolution?arrow_forwardA fireman d = 40.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of ?i = 21.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi = 40.0 m/s, at what height will the stream of water strike the building? m A fireman on the ground sprays water from a fire hose onto a building. The water leaves the hose with velocity vector vi at an acute angle ?i above the horizontal and curves downwards just before it strikes the building at a height h above the ground. The building is a horizontal distance d from the fireman.arrow_forward
- An adventurer paddles a kayak across the current in wild river. She appears to an observer sitting on the riverbank to be travelling directly across the river at 90° to the riverbank, and the water velocity is parallel to the riverbank (in other words, downstream). To do this she must paddle at a constant velocity of 1.8 m/s relative to the water at an angle of 28° from the upstream direction. The river is 76 m wide. What is the speed of the water current? From the given options A 0.80 m/s B 1.6 m/s C 2.2 m/s D 1.9 m/sarrow_forwardThe pilot of an airplane carrying a package of mail to a remote outpost wishes to release the package at the right moment to hit the recovery location A. What angle θ with the horizontal should the pilot’s line of sight to the target make at the instant of release? The airplane is flying horizontally at an altitude of 113 m with a velocity of 291 km/h.arrow_forwardTwo archers are on a contest, who will fire the arrow with the greatest horizontal distance. Archer Miya fires an arrow with an initial velocity of 15 m/s with an angle 39 degrees from the horizontal axis. While Archer Irithel fires the arrow with the same initial velocity and the same origin but has an angle of 45 degrees from the horizontal axis. Who will have the greatest horizontal axis and win the contest? Support your answer with solution and illustration.arrow_forward
- At a football game, imagine the line of scrimmage is the y-axis. A player, starting at the y-axis, runs 7.50 yards, back (in the −x-direction), then 15.0 yards parallel to the y-axis (in the −y-direction). He then throws the football straight downfield 50.0 yards in a direction perpendicular to the y-axis (in the +x-direction). What is the magnitude of the displacement (in yards) of the ball?What if? The receiver that catches the football travels 65.0 additional yards at an angle of 45.0° counterclockwise from the +x-axis away from the quarterback's position and scores a touchdown. What is the magnitude of the football's total displacement (in yards) from where the quarterback took the ball to the end of the receiver's run?arrow_forwardPhysics A football is kicked at 25.0 m/s at an angle of 27.0∘ above the horizontal. Assume it starts 1.00 m above ground level. (Neglect any effects due to air resistance.) Describe the velocity vector of the ball in terms of its ?- and ?-components, ?? and ??, respectively, when it is 4.00 m above ground level and still moving upward. Describe the velocity vector of the ball in terms of its magnitude ? and angle ? above the horizon when it is 4.00 m above ground level and still moving upward.arrow_forwardYou are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics, you ask one of the archers to shoot an arrow parallel to the ground. Unfortunately the archer stands on an elevated platform of unknown height. However, you find the arrow stuck in the ground 56.0 m away, making a 2.00 ∘ angle with the ground. How fast was the arrow shot?arrow_forward
