A5-kg object experiences forces as shown in the diagram. which statement best describes the motion of the object?
a) the object would have a velocity of 6 m/s to the left.
b) the object would have a velocity of 6 m/s to the right.
c) the object would have an acceleration of 6 m/s/s to the left.
d) the object would have an acceleration of 6 m/s/s to the right.

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?
