A 2.00-kg pendulum ball is attached to a light-uniform cable of length 1.20 m that is hanging from the ceiling at an angle of 50.00 to the vertical. When the pendulum ball is released from the rest position, it swings to the very bottom of the motion where it collides head-on with a 1.40-kg block that is initially at rest on a level surface. If the pendulum ball recoils at 1.50 m/s, what is the speed of the block after the collision? e = 50° 1.2 m

**Question 2:**

A 2.00-kg pendulum ball is attached to a light-uniform cable of length 1.20 m that is hanging from the ceiling at an angle of 50.0° to the vertical. When the pendulum ball is released from the rest position, it swings to the very bottom of the motion where it collides head-on with a 1.40-kg block that is initially at rest on a level surface. If the pendulum ball recoils at 1.50 m/s, what is the speed of the block after the collision?

**Diagram Explanation:**

The diagram shows:
- A pendulum consisting of a 2.0 kg ball attached to a cable of length 1.2 m.
- The cable forms an angle of 50° with the vertical.
- The pendulum swings down to collide with a 1.4 kg block resting on a surface.

**Multiple Choice Options:**

a. 4.75 m/s  
b. 5.98 m/s  
c. 6.29 m/s  
d. 3.03 m/s  
e. 3.88 m/s
