A 2.50 kg block starting from rest slides 12.5 m down an inclined plane which makes an angle of 25 degrees with the horizontal. The coefficient of friction between the block and the plane is 0.270. a) What is its potential energy before sliding down the incline? b) What is the velocity of the block after sliding 12.5 m? c) What is its kinetic energy at the foot of the incline? c) Is energy conserve? d) What would the velocity be at the foot of the incline if the friction were negligible? *
