Question

A ball is thron upward with a speed of 120 m/s its speed at midpoint of its apat is

Answer 1

${v}^{2} = {u}^{2} + 2as$
$0 = {120}^{2} + 2gh$
14400 = 2(10)h

h = 720 m

so midpoint will be 360m

${v}^{2} = {u}^{2} + 2as$
$v = u + \sqrt{2gh}$
v = 120+ √20×360

v = 120+112.24

v = 232.24 m/s

Answer 2

Explanation:

V = 232.24m/s ....
