Question 1

A 3.0-kg ball with an initial velocity of (4+ 3) m/s collides with a wall and rebounds with a velocity of (−4 + 3) m/s. What is the impulse exerted on the ball by the wall?

◦
+24Ns

◦
−24 Ns

◦
+18 Ns

◦
−18 Ns

◦
+8.0 Ns


Question 2

A 3.0-kg mass is released from rest at point A of a circular frictionless track of radius 0.40 m as shown in the figure. The mass slides down the track and collides with a 1.4-kg mass that is initially at rest on a horizontal frictionless surface. If the masses stick together, what is their speed after the collision?



◦
2.1 m/s

◦
1.7 m/s

◦
1.9 m/s

◦
1.5 m/s

◦
2.3 m/s
