A particle, moving in a straight line, passes through a fixed-point O. Its velocity v ms -1

Question:

A particle, moving in a straight line, passes through a fixed-point O. Its velocity v ms^-1, t seconds after passing through O, is given by v = 4e^2t + 6e^-3t.

a. Show that the velocity is never zero.

b. Find the acceleration when t = ln 2.

c. Find, to the nearest metre, the displacement of the particle from O when t = 2.
