A particle moves in a straight-line such that its displacement, s metres, from a fixed-point O on

Question:

A particle moves in a straight-line such that its displacement, s metres, from a fixed-point O on the line at time t seconds is given by s = 50[e^-2t – e^-4t].

a. Find the time when the particle is instantaneously at rest.

b. Find the displacement of the particle from O when t = 2.

c. Find the total distance travelled during the first 2 seconds of its motion.
