Question

the greatest height to which a man can throw a ball is h what will be the greatest distance upto which he can throw the stone​

Answer 1

The maximum vertical height that the stone achieves =h

Thus the velocity with which the object s thrown upwards v= 2gh

We know range of projectile R= gv 2

sin2θ

=

gv2

Maximum distance can be covered when θ=45 and sin2θ=1

Therefore R= h

2gh=2h
