A ramp is placed at an angle of 30 degrees (scenario A) and then again at an angle of 60 degrees (scenario B). In each scenario the same cart is elevated to the same height. All frictional forces are negligible. Which scenario requires greater change in energy to elevate the cart? Which scenario requires greater force

1. Scenario A requires greater energy and scenario B requires greater force.

2. Scenario B requires greater energy and scenario A requires greater force.

3. Scenarios A and B require the same energy, but scenario A uses greater force.

4. Scenarios A and B require the same energy, but scenario B uses greater force.

5. Scenarios A and B require the same energy and the same amount of force.
