Let’s analyze and solve each problem in the image to determine whether the objects have **kinetic energy** (energy due to motion) or **potential energy** (energy due to position, usually height above the ground).

### Problem Analysis

1. **Volleyball**
   - Given: Mass = 2.1 kg, Speed = 30 m/s.
   - **Solution**: Since the volleyball is in motion, it has **kinetic energy**.

2. **Baby Carriage**
   - Given: Sitting at the top of a hill 21 m high, Weight = 122 N.
   - **Solution**: The baby carriage is elevated above the ground, so it has **potential energy** due to its height.

3. **Car**
   - Given: Velocity = 40 m/s, Mass = 1120 kg.
   - **Solution**: The car is moving, which means it has **kinetic energy**.

4. **Cinder Block**
   - Given: Sitting on a platform 20 m high, Weight = 79 N.
   - **Solution**: Since the block is elevated, it has **potential energy**.

5. **Bell**
   - Given: At the top of a tower 45 m high, Weight = 190 N.
   - **Solution**: The bell has **potential energy** due to its height.

6. **Roller Coaster**
   - Given: At the top of a 72 m hill, Weight = 966 N.
   - **Solution**: The roller coaster has **potential energy** because of its height.
