A crane at a construction site lifts a concrete block with a mass of 440 kg from the ground to the top of a building with a height of 15.0 m. How much work did the motor of the crane do? (Assume zero energy loss in the lifting mechanism due to friction.)
Explain how long does it take the engine to lift the crate a vertical distance of 18.7 m? Friction in the system is negligible.Please provide step-by-step method to solving the problem.
A 20 000 N truck is acted upon by the force that decreases its speed from 10.00 m/s to 5.0 m/s in 5.0 sec. What is the magnitude of force.
The coefficient of kinetic friction is 0.350. Illustrate what should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?

Two horizontal curves on a bobsled run at the similar angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius to curve is v. What is the safe speed on the larger radius curve.
A meterstick is at rest in an inertial frame S2. If S2 moves with a speed of 0.7c with respect to a rest frame S1, find the length of the meterstick as measured in frame S1 according to classical physics. Reply in units of m.
