You decide to launch a rockof mass m1 using a tube containing a spring of spring constant k. When the spring is at equilibrium, it fills the entire tube. To launch a rock, you push it into the tube, compressing the spring a distance d, at which point a locking mechanism holds the spring(and the rock) in place. When the lockis released, the spring pushes the rock to the end of the tube where it will be launched into the air. The coefficient of kinetic friction between the rock and the inside surface of the tube is given by μk. You setup the launcher at an angle q above the horizontal with the spring end buried such that when the spring is compressed and locked, the rock is at ground level. a)Find the work done on the rock by non-conservative forces as it moves from the point of release to the end of the tube. Express your answer in terms of μk, m1, q, d, and any necessaryconstants. b) Find the velocity of the rockvfas it exits the launch tube in terms of μk, k, m1, q, d, and any…

You push a 2.0-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. Question 1: 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. Question 2: 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 ?
