Forces on an Inclined Plane


Two blocks are at rest on two identical inclined ramps. Their friction coefficients between block and inclined plane are the same. Block A has a mass ten times larger than block B. Both blocks are released at the same time and slide down the ramps. Which statement best describes the situation by the time they reach to the bottom of the ramp?

a)    The velocity of A equals the velocity of B.

b)    The kinetic energy of A equals the kinetic energy of B.

c)     The potential energy of A equals the potential energy of B.

d)    A will move faster than B at the bottom of the ramp.

e)     B will reach to the bottom of the ramp sooner than A.
