The overworked Amazon delivery person is driving up a steep hill with an incline of 26° when a box they forgot to secure starts sliding toward the back of the truck. The 3.5 kg box starts from rest near the drivers seat and slides 2.1 m along the floor to the rear door. The coefficient of kinetic friction between the box and the floor is 0.36. What is the work done by the weight of the box? Wmg = J What is the work done by the Normal Force? WN = What is the work done by the frictional force? W₁ = J J What is the net work done on the box? Wnet = What is the change in kinetic energy for the box? AKE = How fast is the box moving just before it hits the rear door? Vfinal = S

A 20-kg crate is subjected to force F = (2s2 + 3)N, where s is the displacement in meter. If the coefficient of friction between the surface is 0.20, what is the speed of the crate when it travels 10 m starting from rest? F
A light plane of mass 1200 kg makes an emergency landing on a short runway. With itsengine off, it lands on the runway at a speed of 35 m/s. A hook on the plane snags acable attached to a 130 kg sandbag and drags the sandbag along. Now you can consider thesystem as a combined mass along with the sandbag and the plane.Now, the coefficient of friction between the sandbag and the runway is μk = 0.4, and also theplane’s brakes give an additional retarding force of magnitude 1400 N. So our target for thisproblem is to find how far does the plane go before it comes to stop.Assume, when the plane snags the sandbag, the collision is instantaneous.[Hints Think carefully whether you can apply conservation of momentum or not] Find the speed of the plane and sandbag immediately after the collision.
In the given figure below, a 3.0 -kg block is sliding down a 60o-rough incline. The speed of the block is 1.68 m/s at the instant it is 5.25 m from an uncompressed spring located at the other lower end of the incline. The spring has a spring or stiffness constant of 120 N/m and the coefficient of kinetic friction between the block and the incline is 0.35. (a) At what speed (in m/s) will the block strike the spring? (b) What would be the maximum compression (in m) of the spring?
