When an object's speed doubles, its momentum changes by a factor of _____, and its kinetic energy changes by a factor of ______ .

The muon is an unstable subatomic particle witha mean lifetime of 2.2 μs, and about 10,000 muons reach everysquare meter of the earth's surface a minute. A muon has a linear momentum G, and after some short time it decays into two other elementary particles with masses m1 and m2. The energy Q released during the decay is converted entirely into the kinetic energy of the decay products (i.e., into kinetic energy of m1 and m2). Find linear momenta of decay products. Draw a vector diagram showing a range of momenta decay products can take.

Suppose a pitcher throws a ball of 0.15kg with a momentum that equals that of a 2g bullet with a speed of 1800m/s. What is the speed of the ball in km/h?

A bullet moving at a speed of 156 m/s passes through a plank of wood at 143 m/s. Another bullet moving at 113 m/s passes through the same plank at what speed?
