One of the following statements about these objects is correct?
A) It takes the heavier object 10 times longer to reach the bottom of the ramp than the lighter.
B) It takes the lighter object 5 times longer to reach the bottom of the ramp than the heavier.
C) It takes the lighter object 10 times longer to reach the bottom of the ramp than the heavier.
D) The two objects reach the bottom of the ramp at exactly the same time.
E) It takes the heavier object 5 times longer to reach the bottom of the ramp than the lighter.

Question

The acceleration of an object down an inclined plane in the absence of friction and air resistance depends only on the gravitational acceleration and the angle of the incline, not on the mass of the object. Therefore, both objects will reach the bottom of the ramp at the same time.
