... b. In a system of two or more objects, the individual objects could have linear momenta that cancel each other. In this case, the linear momentum of the system would be zero. The kinetic energies of the objects, however, are scalar quantities that are always positive; thus, the total kinetic energy ...

... The average force exerted by a bat on a baseball during the time of contact, 0.002 s, is 6600 N. The mass of a baseball is 0.145 kg and its speed is 75 mph just before the bat collides with it. (a) What is the impulse of the ball hitting the bat? Answer: Let the positive x direction be the direction ...
