A 0.726-kg rope 2.00 meters long lies on a floor. You grasp one end of the rope and begin lifting it up upward with a constant speed of 0.710m/s. Find the position and velocity of the rope's center of mass from the time you begin lifting the rope to the time the last piece of rope lifts off the floor. Plot your results. (Assuming the rope occupies negligible volume directly below the point where it is being lifted)
Astrophysicists in the 1960s tried to explain the existence and the structure of pulsars - extremely regular astronomical sources of radio pulses whose periods ranged from seconds to milliseconds. Estimate the rotation rate of the Sun
A 5.00 g object moving to the right at 20 cm/s makes an elastic head on collision with a 10.0 g object that is initially at rest. Find (a) velocity of each object after the collision and (b) the fraction of the initial kinetic energy transferred to t..
