Question

1. A drag racer constantly accelerates at a rate of 39 m/s2

to increase its speed in a short amount of time. If the drag racer started at rest, what distance did it have to travel to reach a velocity of 33 m/s, E?

Answer 1

$$v^2=v_0^2+2ad,$$ $$d=\dfrac{v^2}{2a}=\dfrac{(33\ \dfrac{m}{s})^2}{2\cdot39\ \dfrac{m}{s^2}}=14\ m.$$
