Passage III
An elevated inclined plane makes, an angle, θ, with a floor. Points A and B on the inclined plane are 0.50 m apart. Point B is at a height H above the floor (see Figure 1).
A solid metal sphere is released from rest at Point A and travels down the inclined plane to Point B. The sphere is in free fall between Points B and C and first hits the floor at Point C, a horizontal distance X from the bottom of the inclined plane.
Figure 2 shows how X varies with 
for different H if the sphere rolls from Point A to Point B. Figure 3 shows h.ow X varies with for different H if the sphere slides from Point A to Point B.
16. Which of the following figures best shows how the sphere's kinetic energy varies with time as the sphere travels down the incline?
Your Answer is
Correct Answer is F
Explanation
In the process of moving downward, the ball is affected by the acceleration of gravity, and the speed becomes faster, so the kinetic energy increases (KE=mv2/2)
