Question
A 10 g rubber ball and a 10 g clay ball are thrown at a wall with equal speeds. The rubber ball bounces, the clay ball sticks. Which ball exerts a larger impulse on the wall? The clay ball exerts a larger impulse because it sticks. The rubber ball exerts a larger impulse because it bounces. They exert equal impulses because they have equal momenta. Neither exerts an impulse on the wall because the wall doesn't move. The two particles are both moving to the right. Particle 1 catches up with particle 2 and collides with it. The particles stick together and continue on with velocity v_f. Which of these statements is true? v_f is greater than v_1. b. v_f = v-1 c. v_f is greater than v_2 but less than v_1.d. v_f = v_2 e. v_f is less than v_2. f. Can't tell without knowing to masses.Explanation / Answer
Solution:
B Rubber ball exerts a larger impulse.
9.4) C vf is Greater than v2 but less than v1
( from the figure observe that v1 is greater than v2 )
