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 plane is 0.1. Calculate the acceleration of the box down the incline. A 75 kg crate is placed on an inclined plane that makes an angle of 45° with the horizontal. The coefficient of friction between the crate and the plane is 0.3. Calculate the acceleration of the crate down the incline.”
