4 (ms) The figure shows an approximate plot of force magnitude F versus time t during the collision of a 38 g Superball with a wall. The initial velocity of the ball is 50 m/s perpendicular to the wall, the ball rebounds dircctly back with approximately the same speed, also perpendicular to the wall. What is the magnitude the change in momentum of the ball? Submt Answer Tries 0/5 Remembering that the impulse can be found by taking the area...

QUESTION 5: A) During Nkuluta's birthday, a selected group of non-quota students decides to take her out for bowling as they reminisce about the rough academic year they have had. During bowling, Deborah throws a ball of mass 12 kg. The ball moves at a speed of 2 m/s along a smooth bowling surface. Nkuluta, then, throws a ball of the same diameter as Deborah's but with a mass of only 4 kg. Nkuluta's ball travels in the same direction...
