A massless cylinder 49 cm long rests on a horizontal frictionless table. The cylinder is divided into two equal sections by a membrane. One section contains nitrogen and the other contains oxygen. The pressure of the nitrogen is twice that of the oxygen. How far will the cylinder move if the membrane is removed?
It then increases it's speed at the rate of 1.55 m/s2. Find out the magnitude of acceleration under these new conditions. Answer in units m/s2.
A seasoned mini golfer is trying to make par on a tricky hole #5, at what speed must the golfer hit the ball to land the ball in the hole
After 803 rev/min is achieved, the motor is disengaged. A friction brake is used to slow the rotational rate to 351 rev/min. Illustrate what is the magnitude of the energy dissipated as heat from the friction brake?
