If the driver of a car wishes to increase his speed from 20 mph to 50 mph while traveling a distance of 528 ft., what constant acceleration should he maintain?

Answer 1

Vo = 20mi/h * 5280Ft/mi * 1h/3600s. =
29.3 Ft/s. = Initial velocity.

V = (50/20) * 29.3 = 73.3 Ft/s.

V^2 = Vo^2 + 2a*d.
Solve for a, Ft/s^2.
