A box is pressed against a horizontal spring, compressing the spring from its relaxed length. The box is then released and the spring launches the box horizontally along a track that ends in a ramp, as shown above. The box has enough speed to leave the ramp, and the box reaches a maximum vertical height above the floor. Assume there is negligible friction between the box and the track and air resistance is negligible. K = spring constant of spring X = distance the spring is compressed M = mass box Theta = angle of ramp from horizontal H = maximum height reached by box The scenario is repeated using a different box with a greater mass. The spring is compressed the same distance x. Indicate how h in this second scenario compares to h in the original scenario, and explain why without mathematically deriving a relation for h. Students derive an equation for h in the original scenario, h= (sin2theta)kx2/2Mg, which may or may not be correct. Is this equation consistent with your claim…
In the figure below, a block of ice slides down a frictionless ramp at angle 0 = 50° while an ice worker pulls on the block (via a rope) with a force Fr that has a magnitude of 45 N and is directed up the ramp. As the block slides through distance d = 0.31 m along the ramp, its kinetic energy increases by 60 J. How much greater would its kinetic energy have been if the rope had not been attached to the block? ---Select--- F. A
Block A (mass 40 kg) and block B (mass 80 kg) are connected by a string of negligible mass as shown in the figure. The pulley is frictionless and has a negligible mass. If the coefficient of kinetic friction between block A and the incline is μ = 0.27 and the blocks are released from rest, determine the change in the kinetic energy of block A as it moves from C to D, a distance of 24 m up the incline.
