Answer 1

Answer:

Explanation:

General equation of a projectile is parabolic.

It is:-

y=xtanø-(1/2){(g*x*x)/(u*u*cosø)},

where ø is the angle of projection,u is the velocity with which a body is projected,and x,y are coordinates of body in the projectile.

At maximum height,

Velocity is 0

=>dy/dx=0

=>2-x=0

=>x=2

Putting x in equation,

Height=(2*2)-((1/2)*2*2)=2m
