Question

15. A stone slides down each of the three frictionless ramps, as shown in the
figure. For which ramp will the speed of the ball be the greatest at the bottom? *
O a. Ramp X
b. Ramp Y
c. Ramp Z
O d. The speed of the stone will be the same

Expert Solution

Step 1

From conservation of energy potential energy at top = kinetic energy at bottom

As the object is same and initial and final positions are also same therefore work done by stone will also be same.

Hence from work energy theorem speed at all ramps will be same
