PLEASE HELP. 1. A baseball pitcher throws a fastball at a speed of 50.0 m/s. The acceleration occurs as the pitcher holds the
ball in his hand and moves it through an almost straight-line distance of 4.2 m. Calculate the acceleration,
assuming it is uniform. Compare this acceleration to the acceleration due to gravity, 9.8 m/s?

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?
