C At the very top before release
D At the bottom of the ramp
Show Worked Solution

Worked Solution

Step 1: Kinetic energy is the energy of a moving object. Step 2: As the ball rolls down, gravitational potential energy is converted into kinetic energy. Step 3: The ball reaches its highest speed at the bottom of the ramp just before it starts to slow down due to friction. Step 4: Highest speed equals maximum kinetic energy.

Correct answer: At the bottom of the ramp
