Zack is driving past his house in FIGURE Q4.1O. He wants to toss his physics book out the window and have it land in his driveway, If he lets go of the book exactly as he passes the end of the driveway, should he direct his throw outward and toward the front of the car (throw 1), straight outward (throw 2), or outward and toward the back of the car (throw 3)? Explain.

- A person standing at the top of a hemispherical rock of radius R kicks a ball (initially at rest on the top of the rock) to give it horizontal velocity vi as shown in Figure P3.56. (a) What must be its minimum initial speed if the ball is never to hit the rock after it is kicked? (b) With this initial speed, how far from the base of the rock does the ball hit the ground?arrow_forwardAs some molten metal splashes, one droplet flies off to the east with initial velocity vi at angle i above the horizontal, and another droplet flies off to the west with the same speed at the same angle above the horizontal as shown in Figure P4.40. In terms of vi and i, find the distance between the two droplets as a function of time. Figure P4.40arrow_forwardA basketball player is standing on the floor 10.0 m from the basket as in Figure P3.47. The height of the basket is 3.05 m, and he shoots the ball at a 40.0 angle with the horizontal from a height of 2.00 m. (a) What is the acceleration of the basketball at the highest point in its trajectory? (b) At what speed must the player throw the basketball so that the ball goes through the hoop without striking the backboard?arrow_forward
- A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one-sixth as large. How does the range of the projectile on the Moon compare with that of the projectile on the Earth? (a) It is one-sixth as large. (b) It is the same. (c) It is 6 times larger. (d) It is 6 times larger. (e) It is 36 times larger.arrow_forwardA golfer hits his approach shot at an angle of 50.0, giving the ball an initial speed of 38.2 m/s (Fig. P4.60). The ball lands on the elevated green, 5.50 m above the initial position near the hole, and stops immediately. a. How much time passed while the ball was in the air? b. How far did the ball travel horizontally before landing? c. What was the peak height reached by the ball? FIGURE P4.60arrow_forwardA stone is thrown horizontally from the highest point of a 95 m building and lands 115 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the highest point of the building, with positive y upwards and positive x in the direction of the throw. How long is the stone in the air in seconds? What must have been the initial horizontal component of the velocity, in meters per second? What is the vertical component of the velocity just before the stone hits the ground, in meters per second? What is the magnitude of the velocity of the stone just before it hits the ground, in meters per second?arrow_forward
- A player kicks a football at an angle of 35° with the horizontal and with an initial velocity of 14.8 m/s. A second player standing at a distance of 26.0 m from the first player in the direction of the kick starts running to meet the ball at the instant it is kicked. (a) At what rate should the second player accelerate to catch the ball? (b) What would be the speed of the second player upon catching the ball? solution with explanation step by steparrow_forwardJonah is reading a novel that describes an athlete participating in an archery competition. The athlete is 186 cm tall and hits an amazing shot where they fire the arrow completely horizontally and it lands 51 m away from them. 1) neglecting air resistance and drag, what must the initial speed of the arrow be? 2) if the arrow was instead fired at an angle of 45°, how far would it have travelled if it was launched at 187m/s?arrow_forwardA puck is moving on an air hockey table. Relative to an x, y coordinate system at time t = 0 s, the x components of the puck's initial velocity and acceleration are v0x = +1.1 m/s and ax = +1.5 m/s2. The y components of the puck's initial velocity and acceleration are v0y = +8.6 m/s and ay = -3.2 m/s2. Find (a) the magnitude v and (b) the direction θ of the puck's velocity at a time of t = 0.50 s. Specify the direction relative to the +x axis.arrow_forward
- Irina, standing on the edge of a cliff, throws a stone at a 40-degree angle above the horizontal with an initial speed of 10.0 m/s. The instant before the stone hits the ground below, it is traveling at a speed of 54 m/s. If Irina were to throw the other rock at a 40-degree angle below the horizontal from the cliff instead, with the same initial speed of 10.0 m/s, what is the magnitude of the velocity of the stone just before it hits the ground? Ignore any effects of air resistance.arrow_forwardA movie stunt driver on a motorcycle can fly over a wide ditch with certain angle and initial speed. However, if he speeds horizontally, will he crosses this ditch? Consider his motion as projectile, and the two sides of ditch have equal altitude. Yes, he will if his initial velocity is big enough No, theoretically he will never cross this ditch It depends on the weather condition It depends on how powerful of his motorcycle Is it 1,2,3, or 4arrow_forwardYou are walking around your neighborhood and you see a child on top of a roof of a building kick a soccer ball. The soccer ball is kicked at 50° from the edge of the building with an initial velocity of 10 m/s and lands 20 meters away from the wall of the building. How tall is the building? Hint: look at your givens in the y-direction. Group of answer choices A. 20m B. 24 m C. 48 m D. 12 marrow_forward
