A m = 10.0 kg box slides down a d = 00 m long ramp that is
raised h = 0 .500 m above the ground (thus the ramp has a θ = 30.0⁰
incline). Assuming the ramp has a coefficient of kinetic friction
of µk = 0.200 and the box is initially at rest, what is
the final speed of the box when it makes it to the bottom of the
ramp? [2.53 m/s]

A box slides down a ramp with a constant acceleration of 0.300 m/s2. The ramp is raised 18.0o above the horizontal. Calculate the coefficient of kinetic friction between the ramp and the box. HINT: Notice that the velocity is not constant as it was in the previous problem. However, the free body diagrams for both of these problems are the same. Use the free body diagram to write out the corresponding Newton's Law equations for x and y in the...
A box with a mass of 8.67 kg slides up a ramp inclined at an angle of 28.3° with the horizontal. The initial speed is 1.66 m/s and the coefficient of kinetic friction between the block and the ramp is 0.48. Determine the distance the block slides before coming to rest. m As shown in the figure below, a box of mass m = 35.0 kg is sliding along a horizontal frictionless surface at a speed vi = 5.55 m/s...
oblem 2: A 5-kg box slides down a ramp. The ramp is l m in length and inclined at an angle of 30° as shown. The box starts from rest at the top. The surface friction coefficient is 0.25 1. Use energy methods to determine the speed of the box at the bottom of the ramp 2. How far does the box slide before stopping on the horizontal floor if it continues to experience the same friction coefficient. 1.00 m...

A block of mass 0.528 kg slides with uniform velocity of 3.60 m/s on a horizontal frictionless surface. At some point, it strikes a horizontal spring in equilibrium. If the spring constant is k = 26.1 N/m, by how much will the spring be compressed by the time the block comes to rest? b. What is the amount of compression if the surface is rough under the spring, with coefficient of kinetic friction µk = 0.411?
