Question

A car is moving on a straight road with constant acceleration. the initial velocity of car is 5 m/s and after 10 seconds its velocity becomes 25 m/s. what is its acceleration

Answer 1

v=25m/s
u=5m/s
t=10 seconds
$a = \frac{v - u}{t} = \frac{25 - 5}{10} = \frac{20}{10} = 2$
So,acceleration is 2m/s^2.
