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?

Answer 1

The displacement of the car, S = 396 m

Step-by-step explanation:

Given data,

The acceleration of the car, a = 2.2 m/s²

The initial velocity of the car, u = 18 m/s

Using the III equations of motion,

S = ut + ½ at²

Substituting the given values in the above equation

S = 18 (2.2) + ½ x 2.2 x (18)²

S = 396 m

Hence, the displacement of the car, S = 396 m
