Does the conservation of momentum follow from Newton’s third law?
Answer to relevant QuestionsSince K = p2/2m, how can kinetic energy be lost in an inelastic collision while the total momentum is still con-served? Explain. Two objects have the same momentum. Do they necessarily have the same kinetic energy? Explain. If a 60-kg woman is riding in a car traveling at 90 km/h, what is her linear momentum relative to (a) The ground and (b) The car? At a basketball game, a 120-lb cheerleader is tossed vertically upward with a speed of 4.50 m/s by a male s cheerleader. (a) What is the cheerleader’s change in momentum from the time she is released to just before being ...An astronaut (mass of 100 kg, with equipment) is headed back to her space station at a speed of 0.750 m/s but at the wrong angle. To correct her direction, she fires rockets from her backpack at right angles to her motion ...
