Question #76826
a boy standing on the top of a building 10m height throws a stone upward with a velocity of 10m/s. Calculate the velocity with which it hits the ground?
Expert's answer
(mv_i^2)/2+mgh=(mv_f^2)/2
v_f=√(v_i^2+2gh)
v_f=√(〖10〗^2+2(9,8)(10))=17 m/s.
v_f=√(v_i^2+2gh)
v_f=√(〖10〗^2+2(9,8)(10))=17 m/s.
