landed 180 metres from the home plate and to have reached a

height of 21.3 metres. Calculate the initial velocity of the

ball.

u^2=v^2-2as

t=?

u=?

v=0

s=180

a=g= -9.8

u^2= √0^2-2x-9.8x180

u= 59.9 m/s

am I using the right equation for this problem. I am not sure if I have to find the angle using the height and the range of the ball to help find the initial velocity. just want to know if this is the right direction with this problem
