A kangaroo can jump up to 5m
Therefore this 5m will be the maximum height of the vertical projectile
Using the formula,
H=u^2/2g
U can find your answer,
When further simplified by taking the value of g as 10m/s^2, we get,
5=u^2/2*10
Therefore the square of initial velocity will be ,
5*20=100
Therefore, u^2=100
Applying square root on b.s
There fore, u=10m/s
Therefore this 5m will be the maximum height of the vertical projectile
