A ball of mass .62 kg has an initial velocity of 7 m/s and moves at an angle of 32° above the +x-direction. The ball hits a vertical wall and bounces off so that it is moving 32° above the -x-direction with the same speed. (a) What is the magnitude of the impulse delivered by the wall? Number (b) What is the direction of the impulse delivered by the wall? OO O O +x-direction -x-direction +y-direction -y-direction None of the above

A handball of mass 0.200 kg, traveling horizontally at 25.0 m/s , strikes a wall and rebounds at 16.0 m/s . What is the magnitude of the impulse in(Ns) imparted on the ball?

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 baseball player pitches a fastball toward home plate at a speed of 41.0 m/s. The batter swings, connects with the ball of mass 335 g, and hits it so that the ball leaves the bat with a speed of 37.0 m/s. Assume that the ball is moving horizontally just before and just after the collision with the bat. (a) What is the impulse delivered to the ball by the bat? Enter a positive value if the impulse is in the direction the bat pushes the ball and  enter a negative value if the impulse is in the opposite direction the bat pushes the ball. ____kg·m/s  (b) If the bat and ball are in contact for 3.00 ms, what is the magnitude of the average force exerted on the ball by the bat? ____kN
