A box of unknown mass is sliding with an initial speed

vi = 5.70 m/s

across a horizontal frictionless warehouse floor when it encounters a rough section of flooring

d = 3.50 m

long. The coefficient of kinetic friction between the rough section of flooring and the box is 0.100. Using energy considerations, determine the final speed of the box (in m/s) after sliding across the rough section of flooring.

As shown in the figure below, a box of mass m = 6.00 kg is sliding across a horizontal frictionless surface with an initial speed vi= 2.40 m/s when it encounters a spring of constant k = 2350 N/m. The box comes momentarily to rest after compressing the spring some amount xc. Determine the final compression xc (in m) of the spring.

A solid, spherical ball slides with speed 4.48 m/s across frictionless ice and then encounters a rough patch with a coefficient of kinetic friction µk = 0.198. The ball is initially not rotating but the friction causes it to start spinning. How far does it slide across the rough spot before it begins to roll without slipping? Express your answer in metres.

A box of mass 730 kg is being pulled at a constant speed across a rough horizontal floor by a constant force, F. The angle of this force above the horizontal is such that the force you apply is a minimum (that is, the amount of force you need to move the box at a constant speed across the floor depends on the angle at which you pull - find the angle which the force is a minimum). Calculate the...

Moving at an initial speed of vi = 2.00 m/s, Jimmy slides from a height of h = 5.00 m down a straight playground slide, which is inclined at θ = 55° above the horizontal. At the bottom of the slide, Jimmy is moving at vf = 9.00 m/s. By determining the change in mechanical energy, calculate the coefficient of kinetic friction between Jimmy and the slide.
