Q. A block with mass m = 5.5 kg slides down an inclined plane of slope angle 10.9 ° with a constant velocity. It is then projected up the same plane with an initial speed 3.85 m/s. How far up the incline will the block move before coming to rest?

Q. A 45-kg crate slides to the left initially at a speed of 5.2 m/s. A rope fulls on it with a tension of 240 N in a direction of 35 degrees above the horizontal to the right. The coefficient of kinetic friction between the crate and floor is .55
