Question

Find the acceleration of a body whose velocity increases from 11ms-1 to 33ms-1 in 10 seconds

Answer 1

Hope it cleared your doubt.

Answer 2

We know, a = v₂ - v₁ / t
Here, (v₂-v₁) = 33 - 11 = 22 m/s
t = 10 s

Substitute their values,
a = 22/10
a = 2.2 m/s²

In short, Your Answer would be 2.2 m/s²

Hope this helps!
