A motorcyclist initially traveling east at 15 meters per second, accelerates uniformly at a rate of 3 meters per second squared east to a velocity of 21 meters per second east. How far did the motorcyclist travel while accelerating?

A- 1.0m

B- 2.0m

C-36m

D-72m

Answer 1

The proper equation of motion is 2ad = v_f² - v_i² or d = ( v_f² - v_i² )/(2a)

Plug into this equation.
