You and your friends push a 400 kg piano across a hardwood floor at a constant speed. You all push it at a 30° angle below the horizontal. You and your friends expand a steady 2500 W for 10 s. If the coefficient of friction between the piano and the floor is 0.2, how far are you able to push the piano?

Two blocks, A and B (with mass 50.0 kg and 1.00 102 kg, respectively), are connected by a string, as shown in Figure P5.86. The pulley is frictionless and of negligible mass. The coefficient of kinetic friction between block A and the incline is k = 0.250. Determine the change in the kinetic energy of block A as it moves from to , a distance of 20.0 m up the incline (and block B drops downward a distance of 20.0 m) if the system starts from rest.

A 4.00-kg particle is subject to a net force that varies with position as shown in Figure P7.9. The particle starts from rest at x = 0. What is its speed at (a) x = 5.00 m, (b) x = 10.0 m, and (c) x = 15.0 m?
The system shown in Figure P5.43 is used to lift an object of mass m = 76.0 kg. A constant downward force of magnitude F is applied to the loose end of the rope such that the hanging object moves upward at constant speed. Neglecting the masses of the rope and pulleys, find (a) the required value of F, (b) the tensions T1, T2, and T3, and (c) the work done by the applied force in raising the object a distance of 1.80 m.

A 50 kg box slides down a 6-meter high plane angled 30o to the horizontal. If the coefficient of friction force between the box and the plane is 0.4 what is the speed of the box at the end of the plane?
A 100kg crate was being towed up the inclined plane where coefficient of kinetic friction on the surface is u=0.25. The box was travelling up with a speed of 6m/s when the cable broke. Determine the speed of the crate 2s afterward. B 6m/s 45°
A vehicle is travelling at 20.0m/s steadily. If the engine provides 7.8x10 W consistently, what is the net resistive force (friction, air resistance, etc.). Answer: P= FAs =7.8×10' = F,x20= F, = 3.9×10’N
Good day.I have a question on physics. I searched for the solution to this problem:A force of 36.ON acclerates a 6.0kg block at 7.0m/s2 along a boriztonal surface. How large is the friction force? and opened two solutions. It actually has the same answers but I am wondering if ff and fk are the same?If ff and fk are the same, then Friction Force and Kinetic Friction are the same?Thank you.
A car traveling at 22 m/s runs out of gas while traveling up a 200 slope. How far up the hill will it coast before starting to roll back down? Assume that car rolls without friction.
A box is placed at the top of an incline at an angle 21.8 degrees to the horizontal. When released the box slides 9.9 meters down the incline. If the kinetic coefficient of friction between the box and the incline is 0.15, what is the final speed of the box? Round your answer to the nearest tenth of a m/s.
A 50kg wooden crate is being pushed up a ramp with a force of 100N (parallel to the ramp) and is initially moving up the ramp at 5.0m/s. The coefficient of kinetic friction is 0.3 and the ramp slopes up at an angle of 20deg from level ground. Will the crate speed up, slow down, or move at a steady pace? Be sure your answer is well supported.
