A 6.23 kg bundle starts up a 32.9° incline with 146 J of kinetic energy. How far will it slide up the incline if the coefficient of kinetic friction between bundle and incline is 0.175? I tried to solve this and used the equation ((146-sin(32.9)*0.175*6.23*9.8)/(9.8*6.23)) and came up with the awnser of 2.2962701829236 which is incorrect. can you tell me where I made my mistake?
A crane at a construction site lifts a concrete block with a mass of m = 482 kg from the ground to the top of a building with a height of h = 23.9 m. How much work did the motor of the crane do?

What formula would I need to use to solve this problem: The rope of a swing is 2.90 m long. Calculate the angle from the vertical at which a 84.0 kg man must begin to swing in order to have the same KE at the bottom as a 1440 kg car moving at 1.41 m/s (3.15 mph). The decrease in gravitational PE is converted into KE as the man falls. This decrease in gravitational PE depends on the change in height.

1. A 23.0 kg child is playing on a swing with a length of 2.5 m. If the swing starts from rest and makes an angle of 40.0◦ with the vertical at the top of the swing, a) determine the child’s speed at the bottom of the swing neglecting friction. b) If the swing has a speed of 2.8 m/s at the bottom, determine the work done by friction during the downswing and, bonus) assuming the force of friction is constant, determine the maximum angle the swing attains on the upswing after passing through the bottom. Hint: Use the approximation that cos θ ≈ 1 − 1 2 θ 2 for angles given in radians.
