what is common to the variation in the range and the hieght of a projectile. I'm thinking of horizontal acceleration pls what do u think

• Elementary mechanics -

My answer is the Rise Time or time to reach max. height.

R = Vo*cosA * (Tr+Tf)
Tr = Tf. Therefore,
R = Vo*cosA * 2Tr.

Tr = Rise time.
Tf = Fall time.
Vo*cosA = Hor. component of initial
velocity.
