Question

2.
A body is thrown vertifally upward with velocity is, the greatest height 'h' to which it will rise is
u
12
d) 28
a)
Os 1 =
b)
c)
28​

Answer 1

Explanation:

A body is thrown vertically upward with velocity 12m/s

So initial velocity =u=12m/s

final velocity v=0

acceleration due to gravity g=-10 m / s²

we know that maximum height=h

=(v²-u²)/2g

=-12²/(2×-10)

=144/20=7.2 m(answer)
