A body is projected up a 25° plane with an initial velocity of 12 m/s. If the coefficient of friction between the body and the plane is 0.25, determine how far the body will move up the plane and the time required to reach the highest point. Also draw a diagram showing the forces acting on the said object.
Ans: 11.31 m and 1.88 s
The block with a mass of 10 kg subjected to a 80N force, has a velocity of 10m/s. Determine the coefficient of kinetic friction between the block and the ground that is required to stop the block after moving 90m.
Ans: 0.87
