As an apple tree is transported by a truck moving to the right with a constant velocity, one of its apples shakes loose and falls toward the bed of the truck. Of the curves shown in Figure CQ3.13, (i) which best describes the path followed by the apple as seen by a stationary observer on the ground, who observes the truck moving from his left to his right? (ii) Which best describes the path as seen by an observer sitting in the truck?

- Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what Initial velocity would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7m/s2 .arrow_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_forwardA rugby player runs with the ball directly toward his opponent’s goal, along the positive direction of an x axis. He can legally pass the ball to a teammate as long as the ball’s velocity relative to the field does not have a positive x component. Suppose the player runs at speed 4.0 m/s relative to the field while he passes the ball with velocity relative to himself. If has magnitude 6.0 m/s, what is the smallest angle it can have for the pass to be legal?arrow_forward
- A toy frog is initially at the origin of a Cartesian coordinate system. Upon leaping, its position after a second is given by P = (5.0 cm)i + (7.0 cm)j + (3.0 cm) k What is the distance (in centimeter) traveled by the toy frog assuming straight-line motion?arrow_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_forwardAn object rolls off a tabletop with a horizontal velocity v0x = 18 m/s. The table is at a height y0 = 1.2 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up. How long, in seconds, is the object falling before it hits the floor?arrow_forward
- A game requires that two children each throw a ball upward as high as possible from point O and then run horizontally in opposite directions away from O. The child who travels the greater distance before their thrown ball impacts the ground wins. If child A throws a ball upward with a speed of v1 = 59 ft/sec and immediately runs leftward at a constant speed of vA = 14 ft/sec while child B throws the ball upward with a speed of v2 = 56 ft/sec and immediately runs rightward with a constant speed of vB = 16 ft/sec, which child will win the game? Calculate the distances sA and sB that each child travels while the respective ball is in the air.arrow_forwardWhich of the following objects is undergoing uniform circular motion> a. An object speeding up at a constant rate while following a circular path. b. An object whose velocity is changing at a constant rate in a given direction. c. An object undergoing acceleration with a constant magnitude directed towards the centre of its circular path. d. An object that is traveling at constant speed around a circular path.arrow_forwardI drive in the positive y direction for 100 seconds at a velocity of 20 m/s. Then I go with a velocity of 8 m/s at an angle of 25 degrees up from the positive x axis for 800 seconds. Then I travel in the positive x direction at 31 m/s for 600 seconds. What will the (x,y) coordinates of my position be at the end. ( make the starting point (0,0)).arrow_forward
- Q.4. A robot lands on Mars. Its x and y coordinates are given by equations:x(t) = 2m –(0.25m/s2)t2y(t)= (1.0 m/s)t +(0.025m/s3) (a).What is the position and distance from landing at t=2 seconds?(b)What is thedisplacement and average velocity during the interval from t=0 s to t= 2?(c).Derivea general expression for its instantaneous velocity vector and find its instantaneousvelocity in its component form as well as in terms of its magnitude.arrow_forwardOn a spacecraft two engines fire for a time of 389 s. One gives the craft an acceleration in the x direction of ax = 3.41 m/s^2, while the other produces an acceleration in the y direction of ay = 7.34 m/s^2. At the end of the firing period, the craft has velocity components of vx = 1860 m/s and vy = 4290 m/s. Find the (a) magnitude and (b) direction of the initial velocity. Express the direction as an angle with respect to the +x axis.arrow_forwardA cameraman on a pickup truck is traveling westward at 20 km/h while he videotapes a cheetah that is moving westward 39 km/h faster than the truck. Suddenly, the cheetah stops, turns, and then run at 46 km/h eastward, as measured by a suddenly nervous crew member who stands alongside the cheetah's path. The change in the animal's velocity takes 1.9 s. What are the (a) magnitude and (b) direction of the animal’s acceleration according to the cameraman and the (c) magnitude and (d) direction according to the nervous crew member?arrow_forward
