A 1.0-kg ball with a speed of 3.0 m/s strikes a 2.0-kg stationary ball. The collision is completely inelastic. (a) Calculate the speed of the balls after collision. (b) Calculate the total kinetic energy change during the collision
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...
A 2.0 kg ball moving east with a velocity of 5.0 m/s collides with a 8.0 kg ball moving west with velocity 2.0 m/s. After collision, the ball of mass 2.0 kg moves with a velocity of 2.0 m/s towards east, what is the velocity of the second ball?
A ball of mass 1.0 kg moving east with a speed of 2.0 m/s collideshead-on with a 2.0-kg ball at rest. If the collision is perfectly inelastic,what will be the speed and direction of each ball after the collision? (Show all Work)
A steel ball whose mass is 2.0 kg is rolling at a rate of 2.8 m/s. What is its momentum?
What is the momentum of an 9.0-kg bowling ball rolling at 1.0 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...
One billiard ball with a mass of 0.50 kg is shot east at 2.5 m/s. A second billiard ball with a mass of 0.25 kg is shot west at 2.0 m/s. The balls have a glancing collision, not a head-on collision, deflecting the first ball by 90% and sending it north at 1.0 m/s. What are the speed of the second ball after the collision? Answer 3.6 m/s Check What is the direction of the second ball after the collision?...
A 6 kg bowling ball rolling at 5 m/s strikes a stationary 4 kg bowling ball. If ball #1 is moving forward at 2 m/s after the collision, what is the speed and direction of ball #2? What is the impulse of the system? If the collision last for .5 seconds, how much force is exerted?
A girl is standing on a raft of mass 48 kg moving at 1.5m/s west. The girl then walks on the raft with a net velocity of 1.0 m/s at 30o north of west. As the girl walks, the net velocity of the raft is 2.0 m/s at 10.5o south of west. Solve for the girls mass using components.
