Question

If velocity of projectile is doubled what happens to the maximum height of projectile?

Answer 1

We know maximum height of a projectile motion is given by

$H=\frac{v_0^2{\sin }^2}{2g}$

Thus from the relation we can say maximum height of the projectile motion depends on velocity of the projectile

directly.

Thus doubling the velocity will double the maximum height if the angle of projectile remains same.
