A man pushes a cart up a hill with a combined load of 1500 kg. The height of the hill is 220m and the total distance to the top of the hill is 200m

a) Calculate the normal force on the cart.

b) If the coefficient of friction up the hill is μk = 0.1, what is the minimum amount of force the man must push the cart to accelerate it constantly up the hill 5 m/s2?

    The 75-kg man pushes on the 150-kg crate with a horizontal force F. The coefficients of static and kinetic friction between the crate and the surface are μs = 0.3 and μk = 0.1, and the coefficient of static friction between the man's shoes and the surface is μ′s = 0.8. What is the greatest acceleration the man can give the crate if the man's acceleration is zero at this instant? I keep getting 1.96 but it says answer is...

    Bob’s 90.0 kg apple cart accidently started rolling down a hill. When Bob caught up with the cart, it was travelling at 2.00 m/s. Bob applied a braking force (parallel to the hill) of 400 N (force F on the diagram) over a distance of 3.50 m. If you ignore air resistance and friction, how fast was the cart going after this distance? The angle from the groud to the begining of the hill is 25 degrees

    You push a box of mass 16.3 kg with your car up to an icy hill slope of irregular shape to a height 4.5 m. The box has a speed 12.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (with no friction) before immediately falling off a sheer cliff to the ground (with no drag). (a) What is the speed of the box at the top of the...

    7. A 1300 kg car drives up a 17 m high hill (the elevation of the hill is 17 meters). During the drive two nonconservative forces do work on the car: the force of friction and the force generated by the car’s engine. The work done by friction adds 331 kJ to the internal energy. The work done by the engine is 634 kJ. (a) What is the change in the car’s kinetic energy? (b) If the car started up...
