04 A 100 g steel ball falls from a height of 1.8 m on to a metal plate and rebounds to a height of
1.25 m. Find:
a. The pe. of the ball before the fall (g = 10 m/s2).
b. Its ke. as it hits the plate,
C. Its velocity on hitting the plate,
d. Its ke. as it leaves the plate on the rebound,
e. Its velocity of rebound.
f. What happens to the rest of the energy

If a clock aboard a space ship traveling at 0.900 c of the speed of light relative to earth chimes once at the beginning of the hour and again when it reads one hour later, how much time would an observer on earth say elapsed between the two chimes?

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
