Question

A car starts from rest and speeds up at 2.2m/s^2 after the traffic light turns green , how far will it have gone when it os traveling at 18m/s?
PLZ write down the steps and the equation you used and thx <3

Answer 1

73.6m

Explanation:

Initial velocity, U = 0

moving velocity, V = 18m/s

 Acceleration = 2.2m/s²

Unknown:

Distance covered = ?

Solution:

 we have to use the appropriate equation of motion to solve this problem

           V² = U² +2as

    V is the final velocity

    U is the initial velocity

     a is the acceleration

     s is the distance

  since u = 0

             V² = 2as

             18²  = 2 x 2.2 x s

            324 = 4.4s

                  s = $\frac{324}{4.4}$ = 73.6m
