Question

Find the acceleration of a car a velocity of 60 m/s in a distance 360 m

Answer 1

Explanations & Calculations

• Assuming it started at rest and travelled 360m before gaining that velocity 60m/s at constant acceleration, apply $v^2=u^2+2as$ to calculate the acceleration.

$\qquad\qquad \begin{aligned} \small (60\,ms^{-1})^2&=\small 0^2+2a(360\,m)\\ \small a&=\small 5\,ms^{-2} \end{aligned}$
