“A 20 kg box is placed on an inclined plane that makes an angle of 25° with the horizontal. The coefficient of friction between the box and the plane is 0.3. Calculate the acceleration of the box down the incline. A 100 kg crate is on an inclined plane with an angle of 40° with respect to the horizontal. The coefficient of friction between the crate and the plane is 0.15. Calculate the acceleration of the crate down the incline.”
