Question

a body starts with initial velocity 10 metre per second square a velocity of 20 metre per second in 5 second find the acceleration of the body​

Answer 1

Given: u=10, v= 20 and t= 5 sec

We have the 1st kinematic equation:

$v = u + at$

Putting values in the equation

$20 = 10 + 5a$

$5a = 10$

$a = 2 \frac{m}{ {s}^{2} }$
