Q1. Suppose that it takes 16.9 hours to drain a container of 62.0m3 of water. What is the "mass flow rate," in kg/s, of water from container?
Q2. A shell is fired from the ground with an initial speed of 1.76 103 m/s at an initial angle of 51° to the horizontal.
(a) Neglect air resistance; find the shell's horizontal range.
(b) Find out the amount of time the shell is in motion.
Q3. One mole of an ideal gas is heated so that T = AP2, where A is a constant and P is the pressure. The temperature changes from T0 to 4T0. Find out the work completed by the gas. (Use the following as necessary: T0, P0, and V0.)
A 1050 kg car carrying four 84 kg people travels over a rough "washboard" dirt road with corrugations 4m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude while its speed is 24km/h. The car now s..
