The velocity V (m/s) of a missile varies with time according to the relation: V = Vo(1-e't'k), where V0 is the initial velocity, t (s) is time since firing and k = 60 seconds. Calculate: 1. V0 correct to the WI, m/s, where V = 8 (m/s) and t = 30 seconds and k = 60 seconds. 2. The distance travelled by the missile at t = 142 seconds
