Question1

A student has two ramps, both of that are at an angle 25°. Ramp 1 is frictionless and ramp 2 has friction. The student also has two blocks, one for each ramp. She pushes blocks up the ramps with the similar initial velocity. The block on ramp 2 only travels a fraction f = 0.610 as far as the block on ramp 1 before coming to a stop (i.e. d2 = 0.610*d1). Find out the coefficient of sliding friction between the block and ramp 2. Utilize three significant figures when entering your answer.

Question2

A student who weighs 460 N is wearing a backpack that weighs 77 N. The student is standing still on level ground. Give the answers to following questions in Newton’s. Memorize, enter only number; do not try to enter the units.
