Question

if a particle can be thrown to maximum range of 400m then maximum height is

Answer 1

Maximum range R=X÷g
where,
X=maximum height
g=acceleration due to gravity=9.8m/s^2 (constant value)

Given, R=400 m
and we know,g=9.8m/s^2
x=?

Now the formula can be written as,
X=R×g

X=400×9.8

X=3920 m

The maximum height of a particle=3920 m
