... In other words, about 99.4% of the initial kinetic energy is lost. (c) The rod will momentarily stop when it gets to a point where all its initial kinetic energy has been transformed into gravitational potential energy. We can choose any height for h = 0, so let’s choose the initial horizontal heigh ...

... The gravitational force is a conservative force. Thus, the work done by the gravitational force on a particle moving from an initial point i to a final point f is independent of the path taken between the points. The change DU in the gravitational potential energy from point i to point f is given by ...

... 2) A 30 kg girl who is running at 3 m/s jumps on a stationary 10 kg sled on a frozen lake. How fast does the sled then move? 3) Two people, one of mass 75 kg and the other of mass 60 kg, sit in a rowboat of mass 80 kg. With the boat initially at rest, the two people, who have been sitting at opposi ...

... Ex 7-1 Force of a tennis serve For a top player, a tennis ball may leave the racket on the serve with a speed of 55 m/s (about 120 mph). If the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4x10-3 s), estimate the average force on the ball. Would this force be large ...
