... 1. C If p=mv and KE= ½ mv², and we want to put these two together so that way we are left with v. You see that if we divided KE by p, m would cancel out, and one v, and we would be left with ½ v, so v= 2KE/p. If we put the values from the table, you will see that C is the correct answer. 2.

Initially, the mass is released 1 ft below equilibrium with a downward velocity of 5 ft/s, and motion is damped by a force numerically equal to 2 times the instantaneous velocity. If motion is driven by an external force f (t) ...
