As you may know, if you drop an object and it is affected little by air resistance, the acceleration is 9.8m/s^2. do you think accleration down the ramp is more or less than is 9.8m/s^2?

Acceleration down a ramp is less than 9.8 m/s^2

Explanation:

The force responsible for accelerating down an object is the force of gravity (the weight of the object), given by

where m is the mass of the object and g=9.8 m/s^2 is the acceleration due to gravity.

When an object is along a ramp, the acceleration is along the ramp: therefore, it is due not to the whole force of gravity, but only to its component acting along the ramp. The component of the weight acting along the ramp is

where is the angle of the ramp. As a consequence, the acceleration of the object is

and since , it means that the acceleration is less than 9.8 m/s^2.

the answer is b
