A 130-g baseball, moving along the x-axis with speed 29.0 m/s strikes a fence at a 45 degree angle and rebounds along the y-axis with unchanged speed. Give x and y components of its change in momentum.
A 12.5-kg horizontal plank 4.00 m long rests on two supports, one at the left end and a second 1.00 m from the right end
A spring is oscillating with a frequency of 1.7Hz. 3.9 seconds after the spring is released it is -20cm from equilibrium. Find the amplitude of the spring
M1 is five times more massive than M2. One force acts on the hanging mass, but the net force acts on both masses. Once you have the acceleration, you can compute the distance.
