A tennis racket collides with a tennis ball and sends the ball shooting away at a high speed. What can we say about the forces of collision between the two? The forces are equal in both magnitude and direction The forces are equal in magnitude but opposite in direction The force the ball applies on the racket is larger than the force the racket applies on the ball The force the racket applies on the ball is larger than the force the ball applies on the racket

Which of the following statements ARE correct? O Momentum is always conserved O Momentum is conserved only when there is no net external force applied on the system O Momentum is always conserved during collisions between isolated objects O Kinetic energy is conserved during all kinds of collisions Kinetic energy is not conserved during inelastic collisions O Kinetic energy is not conserved during elastic collisions

During a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball? O 167N 0400N O 13.3 N 107 N

A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 5.60 m/s in 0.812 s. What are the magnitudes of the linear impulse and the average total force experienced by a 62.0 kg passenger in the car during the time the car accelerates? linear impulse |kg-m/s average force

A 72-kg boy and a 48- kg girl, both wearing ice skates face each other at rest on a skating rink. The boy pushes the girl, sending her eastward with a speed of 6.8m / s . What is the speed and direction of the boy?

A tennis ball, with a velocity of 6.2 m/s, impinges at an angle of ? = 30˚ (with respect to the vertical line) on a fixed and smooth horizontal table. Given the coefficient of restitution is 0.5, determine the velocity and the direction of the ball after collision with the table

Ball 1 of mass 0.12 kg makes an elastic head-on collision with ball 2 of unknown mass that is initially at rest. If ball 1 rebounds at one-third of its original speed, determine the mass of ball 2.

A 0.250 kg toy car moving with a speed of 0.860 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

Jenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward in her bumper car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop. What is the direction of the force exerted on Jenny's car during the collision?

A 1000 kg car moving westward with a velocity of 10 m/s collides with a utility pole and is brought to rest in 0.25 s.  Find the magnitude of the force exerted on the car during the collision.
