a) The two objects reach the bottom of the ramp at exactly the same time.
b) It takes the heavier object 5 times longer to reach the bottom of the ramp than the lighter.
c) It takes the lighter object 10 times longer to reach the bottom of the ramp than the heavier.
d) It takes the heavier object 10 times longer to reach the bottom of the ramp than the lighter.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
