Question

A player wants to jump a height of 5 m in a game of pole-volt. What should be his speed? ( ans: 10m/sec)

Answer 1

given that h = 5 m , g= 10 m sec ^-2

h = (1/2)V^2/g
5=(1/2)v^2/10
10= v^2/10
v^2=100
v=10 m/sec ans

I hope it help you

Answer 2

Hello Mate

Here is your solution

Given,

Height = 5m

g = 10 m/s

Now,

From the formula

$height \: = \frac{v2}{2g}$

Put the given value on formula

$= = > \: \: \: 5 = \frac{ {v}^{2} }{2 \times 10}$

$= = > \: \: 5 = \frac{ {v}^{2} }{10 \times 2}$

$= = > \: {v} = 20 \times 5$

$= = > v = \sqrt{100}$

$= = > \: v \: = 10$

Therefore,

The required speed will be 10m/sec.
