Ball A, rolling west at 3.2 m/s, has a mass of 1.0 kg. Ball B has a mass of 2.4 kg and is stationary. After colliding with ball B, ball A moves south at 2.0 m/s.
1. A ball of mass 14 kg is rolling towards the wall at 5.00 m/s. After the impact with the wall, the ball rolls back at 4.60 m/s. Calculate the magnitude of change in momentum of the ball. 2. A typical rifle has a mass of 3.0 kg. A bullet in that rifle has a mass of 3.0 g. After the bullet is fired, it has a speed of 100 m/s. Calculate the magnitude of average force exerted by the...
A soccer ball of mass 0.39 kg is rolling with velocity <0, 0, 2.4> m/s, when you kick it. Your kick delivers an impulse of magnitude 2.4 N·s in the -x direction. The net force on the rolling ball, due to the air and the grass, is 0.32 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s after you...
What is the momentum of an 9.0-kg bowling ball rolling at 1.0 m/s
A soccer ball of mass 0.50 kg is rolling with velocity 0, 0, 1.8 m/s, when you kick it. Your kick delivers an impulse of magnitude 1.2 N · s in the −x direction. The net force on the rolling ball, due to the air and the grass, is 0.22 N in the direction opposite to the direction of the ball's momentum. Using a time step of 0.5 s, find the position of the ball at a time 1.5 s...
