A frictionless incline at an angle of 400deg with respect, Ask an Expert

Academics

A frictionless incline at an angle of 40.0° with respect to the horizontal has a block of mass 50.0 kg attached by a mass less rope-pulley assembly to a mass weighing 55.0 kg hanging in the air. What is the acceleration of the mass on the incline? What is its speed after a displacement of 15.0m? What is the length of time it took to cover the 15.0m?
