One ball has twice the mass of the other. The lighter one has one fourth as much kinetic energy as the other A rope exerts a force F on a 20.0 kg crate. Refer to the information above. In the figure below, the cue ball strikes another ball such that it follows the path shown. Refer to the information above.
M balances the boy B on a very light teeter-totter, as shown below.
Refer to the information above. A 0.5-kg mass is pressed against the spring, compressing it 0.20 m from is equilibrium position. The mass is then released. The same mass is attached to the same spring and placed on a horizontal frictionless surface. The mass is then pulled so that the spring stretches to a total length of 0.10 m.
