A ball of mass 1.6 kg is tied to the end of a 0.40 m string to form a pendulum. This pendulum is released from rest when the string is horizontal. At the lowest point of the course, when the ball moves horizontally, it collides with a 0.80 kg block initially at rest on a horizontal frictionless surface. The speed of the block just after the collision is 3.0 m / s. What is the speed of the ball just after the collision? Answers: a) 1.7 m/s b) 1.1 m/s c) 1.5 m/s d) 1.3 m/s e) 2.1 m/s
