Question

2. The figure below shows the acceleration of a 10 kg package that is accelerated to a maximum acceleration of a. = 20 m/s2 . How much work did the force used to accelerate the package do in order to move it from 0 m to 8 m?

Answer 1

Explanations & Calculations

$\qquad\qquad \begin{aligned} \small W&=\small F \Delta s\\ &=\small (ma) \Delta s\\ &=\small 10kg\times20ms^{-2}\times8\,m\\ &=\small 1600\,J \end{aligned}$
