Physics 11(ramp problem)

Question

it takes a force of 250n to push the block shown here up the incline at a constant speed. assume that the applied force is parallel to the surface of the incline. the block has a mass of 25 kg and the character on top of the block has a mass of 5.0 kg. given that frictional forces can be ignored, determine the angle of the incline.

Answer 1

The force that an object's weight exerts along an incline is mgsin(θ). This is equal to the force that must must be exerted up the incline in order to have constant velocity (Fnet = 0)

F (given) = mgsin(θ) and solve for theta, the angle of the incline.
