Question

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

Answer 1

Since acceleration is constant

So the distance moved in constant acceleration will be given as

`d = (v_f + v_i)/(2) t`

as we know that

`v_f = 20 m/s`

`v_i = 0`

t = 17 s

so distance moved is given by

`d = (0 + 20)/(2)(17)`

`d = 170 m`

so distance moved will be 170 m
