# Another physics K**LER prob?

A crate (A) of 13 kg on a frictionless inclined plane is attached to another crate (B) of 22 kg by a massless rope. The rope passes over an ideal pulley so that B is suspended in air. The plane is inclined at θ = 24.0°. Use conservation of energy to find how fast B is moving if after A has moved 1.4 m along the...

The plane is inclined at θ = 24.0°. Use conservation of energy to find how fast B is moving if after A has moved 1.4 m along the incline , starting from rest.

okay, this question has a picture that really doesn't give much info. It is a right triangle, A is on the hypotenuse, B is on the opposite or (vertical 90°), & θ = 24.0°.

the ans is roughly around 3.62 m/s, help me get to it

thanks
