Question

A car waiting at a traffic light starts to move with a constant acceleration of `2.0 m//s^(2)` when the light truns green. Two second later, a truck moving in the same direction passes the light at a constant speed of `25 m//s` and soon passes the car. Soon the car passes the truck:
(a) How long after the car starts do the two overtakings occur ?
(b) How far from the light does each take place?

Answer 1

Correct Answer - (a) 2.19 s and 23 s; (b) 4.8 m and 520 m
For `v = a xx t`
`s = (1)/(2) xx at^(2)`
For truck `d = v xx t`
