Assignment#6: Work and Energy
A box of mass m=12.0 kg is located at the top of a ramp of height h=8.00 m, as shown in the figure. The coefficient of kinetic friction between the ramp and the box is μk=0.5. You give the box a push so that it starts sliding down with an initial speed of 3.00 m/s. The box continues its motion on a rough horizontal surface for 5.00 m until it hits a spring of spring constant k=150. N/m and fully compresses it by 50.0 cm and comes to rest. What is the coefficient of kinetic friction between the horizontal surface and the box?

As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...

Use work and energy to find an expression for the speed of the block just before it hits the floor if: the coefficient of kinetic friction for the block on the table is mu_k. the table is frictionless. A 5.0 kg box slides down a 5.0-m-high frictionless hill, starting from rest, across a 2.0-m-wide horizontal stir face, then hits a horizontal spring with spring constant 500 N/m. The other end of the spring is anchored against a wall. The ground...

3.0 - 6.00 m ASSO 13.0-kg block is released from point A with initial speed of -2.0 m/s ( block is given a push up or down the ramp). The track is frictionless except for the portion between points B and C which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,000 N/m, and compresses the spring 0.20 m from its equilibrium position before coming to rest momentarily. Determine the...

A box of mass m = 2.00 kg is positioned on a ramp at an angle θ. The length of the ramp (minus the width of the base of the box) is d = 3.00 m. The surface of the ramp has a coefficient of static friction μs = 0.500 and a coefficient of kinetic friction μk = 0.350. The angle θ is slowly increased until the box starts to slide down the ramp. Calculate the angle θmax at which...

A 5.80-kg box sits at rest at the bottom of a ramp that is 8.20 m long and that is inclined at 40.0 ∘ above the horizontal. The coefficient of kinetic friction is μk = 0.40, and the coefficient of static friction is μs = 0.43. What constant force F , applied parallel to the surface of the ramp, is required to push the box to the top of the ramp in a time of 4.00 s ? Express your...
