Question

A particle moving in a straight line has a displacement, $t$ seconds after passing a fixed point $O$, given by the formula $s = te^{-0.2t}$. Find: The velocity, in $m/s$, of the particle when $t = 4$ The acceleration of the particle when $t = 2$

Accepted Answer

(a) $0.2e^{-0.8}\text{ m/s}=0.0899\text{ m/s}$ (b) $-0.32e^{-0.4}\text{ m/s}^2=-0.215\text{ m/s}^2$
