You push a 5.0-kg block up a ramp by exerting a 100-N force directed parallel to the ramp, which is at a 30∘ angle to the horizontal. Part A Ignoring any effects due to friction, calculate the block's speed when you have pushed it 3.0 m if its velocity when you began pushing was 2.0 m/s up the slope. Express your answer with the appropriate units.   Part B Now consider friction. If the coefficient of kinetic friction between block and ramp is μ = 0.25, what is the block's speed after you have pushed it 3.0 m ? Express your answer with the appropriate units   Part C With this value of μk how much farther up the ramp does the block move once you stop pushing? Express your answer with the appropriate units.
