Here, u= 15m/s, v=0,g= 9.8 m/s^2,h=?

From v^2-u^2=2gh

h= v^2-u^2/2g

= 0–15^2/2*(-9.8)

=11.48m

Answer :-

The ball will reach upto the height of 11.46 metres.

Explanation :-

Given :

u = 15 m/s
v = 0
g = -9.8 m/ ${s}^{2}$

Now,

${v}^{2} = {u}^{2} + 2gs \\ = > s = \frac{ {v}^{2} - {u}^{2} }{2g} \\ = > s = \frac{0 - {(15)}^{2} }{2 \times ( - 9.8)} \\ = > s = \frac{ - 225}{ - 19.6} \\ = > s = \frac{225}{19.6} \\ = > s = 11.48 \: m$

•°• The ball will reach upto the height of 11.48 metres.
