Question

A 20kg object is attached by a thin rope to a 50kg mass that hangs over a frictionless pulley at the top of a 25 degree incline. (Use g = 10m/s2 )

a) Calculate the magnitude and direction of the component of the 300 N force that

accelerates the block horizontally

b) If the acceleration of the block is 2 m·s−2, calculate the magnitude of the

frictional force acting on the block.

c) Calculate the vertical force exerted by the block on the plane.​
