Q
Q: A ball rolls down a ramp of height h. If it has a mass m and radius r, what is the potential energy at the top?
Solution:
The potential energy at the top of the ramp is given by PE = mgh.
Steps: 5
Show Steps
Step 1: Identify the height of the ramp, which is given as 'h'.
Step 2: Identify the mass of the ball, which is given as 'm'.
Step 3: Understand that potential energy (PE) is the energy an object has due to its position.
Step 4: Recall the formula for potential energy at a height, which is PE = mgh.
Step 5: Substitute the values of mass (m), gravitational acceleration (g), and height (h) into the formula.
