Answer to Question #267042 in Physics for Kitty

Question

car from rest is moving at a velocity of 86 km/hr in 10 seconds. Determine the acceleration of a car.

Answer 1

Given:

$v_i=0$

$v_f=86\:\rm km/h=23.9\: m/s$

$t=10\:\rm s$

The acceleration of the car

$$a=\frac{v_f-v_i}{t}=\frac{23.9-0}{10}=2.39\:\rm m/s^2$$
