To annoy his son-in-law Jerry, Rick takes a block with a mass of 4.25kg and places it on a smooth horizontal surface compressing a spring 0.525m from its equilibrium position. The block is released from rest and slides across the horizontal surface and travels 4.00m up an incline with a coefficient of kinetic friction of 0.410 that makes an angle of 25.0° with respect to the horizontal. If the block has a velocity of 2.95m/s when it has traveled the 4.00m up the incline to press a button on a Mr. Meeseeks box. What would the stiffness of the spring need to be in Newtons per meter?
