A 1.6 kg ball is attached to the end of a 0.45 m string to form a pendulum. This pendulum is released from rest with the string horizontal. At the lowest point of its swing, when it is moving horizontally, the ball collides with 0.80kg 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? 1) 1.7 m/s 2) 1.1 m/s 3) 1.5 m/s 4)1.3 m/s

A 1.6 kg ball is attached to the end of a 0.45 m string to form a pendulum. This
pendulum is released from rest with the string horizontal. At the lowest point of its
swing, when it is moving horizontally, the ball collides with 0.80kg block initially, at
rest on a horizontal frictionless surface. The speed of the block just after the collision is
