Acar accelerates at a rate of 3.0 m/s^2. if it’s initial speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s? show work

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
