A 1 kg block slides down an incline. The incline is 5 m long and has an angle of 25 with the horizontal. There is friction between the block and the incline, with coefficient k = 0.15. Initially, at the top of the incline, the block is moving at 2.5 m/s. At the end of the incline there is a horizontal surface (k = 2.5). 1. Draw a free body diagram of the block on the incline. 2. What is the friction force exerted by the incline on the block? 3. How fast is the block at the bottom of the incline? 4. How far does the block go along the horizontal surface before it stops? Show and explain all the steps of your solution. You must use the work-energy theorem, do not use concepts that have not been introduced and explained in class yet.
