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.)
A tree falls on a bicycle path 40 m ahead of a cyclist traveling at 16 m/s, how far from the fallen tree will she be when she stops
illustrate what minimum projection angle would achieve this result? What maximum pro- jection angle would achieve this result?
A mass m = 90 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius R = 18.8 m and finally the flat straight section at the same height as the center of the loop (18.8 m off the ground). Because the mass would not..

As a engineer, you are designing a heat pump that is capable of delivering heat at the rate of 22 kW to a house. The house is located where, in January, the average temperature is 10°C.
The temperature of the surface of a certain star is 7500K. Most hydrogen atoms at the surface of star are in the electronic ground state. What is the approximate fraction of hydrogen atoms that are in the first excited state (and therefore could e..
