A table-tennis ball is thrown at a stationary bowling ball. The table-tennis ball makes a one-dimensional elastic collision and bounces back along the same line. Compared with the bowling ball after the collision, does the table-tennis ball have (a) a larger magnitude of momentum and more kinetic energy, (b) a smaller magnitude of momentum and more kinetic energy, (c) a larger magnitude of momentum and less kinetic energy, (d) a smaller magnitude of momentum and less kinetic energy, or (e) the same magnitude of momentum and the same kinetic energy?

A professional boxer hits his opponent with a 1075 N horizontal blow that lasts 0.190 s. The opponent's total body mass is 105 kg and the blow strikes him near his center of mass and while he is motionless in midair. (a) Determine the impulse (in kg m/s) the boxer imparts to his opponent by this blow. kg m/s (b) Determine the opponent's final velocity (in m/s) after the blow. m/s (c) Calculate the recoil velocity (in m/s) of the opponent's 5.0 kg head if hit in this manner, assuming the head does not initially transfer significant momentum to the boxer's body. m/s

A cue ball traveling at 6.57 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30.0° with its original direction of travel. (a) Find the angle between the velocity vectors of the two balls after the collision.   (b) Find the speed of each ball after the collision.

A baseball of mass 0.145 kg is pitched at a speed of 39.0 m/s, the ball is hit back towards the pitcher with a speed of 52.0 m/s. I) What is the magnitude of the impulse delivered by the bat to the baseball? (a) 13.2 kg m s (b) 1.89 kg m s (c) 13.0 kg m s (d) 943 kg m s II) Find the magnitude of the average force, in kN, exerted by the bat on the ball if the two are in contact for 2.00x10° s.

A cart with mass 330 g moving on a frictionless linear air track at an initial speed of 1.8 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 1.1 m/s. (a) What is the mass of the second cart? (b) What is its speed after impact? (c) What is the speed of the two-cart center of mass?

Two objects, both with a mass of 1.72 kg are sliding across a horizontal, frictionless surface toward each other. If mass 1 has an initial velocity of 4.17 m/s i  and mass 2 has an initial velocity of -2.08 m/s i, what is the change in total kinetic energy if they undergo a perfectly inelastic collision? Assume that total momentum is conserved.

two blocks (m1 and m2) are each released from rest at a height of h = 3.98 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.25 kg, determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure.

A billiard ball moving at +10.0 m/s along the x-axis collides with a second billiard ball, of identical mass, at rest.  After the collision, the first (incoming) ball moves off with a velocity of 7.7 m/s at an angle of 40 degrees above the x-axis.  What is the velocity of the second ball after the collision?

As shown in the figure below, object m1 = 1.55 kg starts at an initial height h1i = 0.295m and speed v1i = 4.00 m/s, swings downward and strikes (in an elastic collision) object m2 = 4.65 kg which is initially at rest. Determine the following. (a) speed of m1 just before the collision. m/s (b) velocity (magnitude and direction) of each ball just after the collision (Assume the positive direction is toward the right. Indicate the direction with the sign of your answer.) m/s (m1) m/s (m2) (c) height to which each ball swings after the collision (ignoring air resistance)  m1=            M m2=            M

A tennis player receives a shot with the ball (0.0600 kg) traveling horizontally at 50.4 m/s and returns the shot with the ball traveling horizontally at 31.4 m/s in the opposite direction. (Take the direction of the ball's final velocity (toward the net) to be the +x-direction.) (a) What is the impulse delivered to the ball by the racket? magnitude N-S direction Select-v (b) What work does the racket do on the ball? (Indicate the direction with the sign of your answer.)
