Physics

Its acceleration is 1.25 meters/second2 ( 1.25 m/s^2 )

Explanation:

Acceleration is defined as the rate of change of velocity per unit time:

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time taken

In this problem, the initial velocity of the car is zero: u=0. The final velocity is v=5 m/s, and the time taken is t=4 s, so the acceleration is

$a=\frac{v-u}{t}=\frac{5 m/s-0}{4 s}=1.25 m/s^2$
