Practice Problems: In Physics Abhay Kumar Pdf

$= 6t - 2$

A body is projected upwards from the surface of the earth with a velocity of $20$ m/s. If the acceleration due to gravity is $9.8$ m/s$^2$, find the maximum height attained by the body.

(Please provide the actual requirement, I can help you) practice problems in physics abhay kumar pdf

At maximum height, $v = 0$

Given $u = 20$ m/s, $g = 9.8$ m/s$^2$

$0 = (20)^2 - 2(9.8)h$

Using $v^2 = u^2 - 2gh$, we get

Given $v = 3t^2 - 2t + 1$
