1.	a stone is thrown vertically upward with an intial velocity u frok the top of a tower of height 12 u squre by g wiht what velocity does the stone reach the ground
Answer» GIVEN: H=12u^2/g INITIAL vel.=u using FORMULA v^2=u^2-2as v^2=u^2+2g12u^2/g (since a= -g and s=h) so v=5u ans.

a stone is thrown vertically upward with an intial velocity u frok the top of a tower of height 12 u squre by g wiht what velocity does the stone reach the ground

Answer»

GIVEN: H=12u^2/g

INITIAL vel.=u

using FORMULA v^2=u^2-2as

v^2=u^2+2*g*12u^2/g (since a= -g and s=h)

so v=5u ans.
