Quick comprehension check
“A 25 kg box is placed on an inclined plane that makes an angle of 20° with the horizontal. The coefficient of friction between the box and the incline is 0.35. Calculate the acceleration of the box down the incline. Show your work. A 75 kg crate is on an inclined plane with an angle of 45°. If the coefficient of friction between the crate and the plane is 0.15, determine the acceleration of the crate. Show your work.”
