Question 25

A particle’s displacement, sss metres, from a fixed origin at time ttt seconds, is given by the equation

s=4e0.2t s = 4e^{0.2t} s=4e0.2t

Find an expression for the velocity, v m s−1v \text{ m s}^{-1}v m s−1, of the particle at time ttt seconds.

Select the correct answer from the options below:

v=20e0.2tv = 20e^{0.2t}v=20e0.2t

v=0.8e0.2tv = 0.8e^{0.2t}v=0.8e0.2t

v=0.8te0.2tv = 0.8te^{0.2t}v=0.8te0.2t

v=0.5e0.2tv = 0.5e^{0.2t}v=0.5e0.2t
