if a ball is shot horizontally with an initial speed of 10m/s. what is the acceleration...
A ball is shot horizontally from the top of a building with an initial speed of 45 m/s. The ball lands 180 m horizontally from the release point. a) Explain how you can find the time the ball is in the air and find the time. b) Explain how you can find the height of the building and find the height.
A bullet (0.05kg) is shot horizontally at 10m/s toward a stationary wooden block (3kg). The bullet and block undergo a perfectly inelastic collision. What is the speed of the system after the collision? If the coefficient of friction between the system and floor is 0.3, how far will it travel before coming to rest after the collision?
A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 52.0 m/s and returns the shot with the ball traveling horizontally at 32.0 m/s in the opposite direction. (Assume the initial direction of the ball is in the -x direction.) (a) What is the impulse delivered to the ball by the racquet? ? (b) What work does the racquet do on the ball? How many Joules?
A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 50.0 m/s and returns the shot with the ball traveling horizontally at 38.0 m/s in the opposite direction. (Assume the initial direction of the ball is in the -xdirection.) (a) What is the impulse delivered to the ball by the racket? (b) What work does the racket do on the ball?
In the figure, a 0.400 kg ball is shot directly upward at initial speed 31.5 m/s. What is its angular momentum about P, 1.09 m horizontally from the launch point, when the ball is (a) at maximum height and (b) halfway back to the ground? What is the torque on the ball about P due to the gravitational force when the ball is (c) at maximum height and (d) halfway back to the ground? Ball (a) Number Units (b) Number...
