Question

A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car's acceleration is (?)

meters/second^2

Answer 1

3m/s^2

Step-by-step explanation:

The equation of motion is given by:

V=U +at where V is the final velocity, U is the initial velocity, a is the acceleration and t is the time for which the object underwent acceleration.

16=4 + a*4;

Solving for a gives a = 3m/s^2
