Two identical 0.50-kg carts, each 0.10 m long, are at rest on a low-friction track and are connected by a spring that is initially at its relaxed length of 0.50 m and is of negligible inertia. you give the cart on the left a push to the right (that is, toward the other cart), exerting a constant 4.5-n force. you stop pushing at the instant when the cart has moved 0.55 m . at this instant, the relative velocity of the two carts is zero and the spring is compressed to a length of 0.30 m. a locking mechanism keeps the spring compressed, and the two carts continue moving to the right. by what amount do you change the system's kinetic energy?

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
