AN OBJECT IS DROPED FROM 10METER OF THE GROUND CALCULATE ITS VELOCITY AT THE MIDDLE POINT & JUST BEFORE TOUCHING THE GROUND ?
ayeshaoct:
What is its acceleration?
And time?
no time ; & no accelaration . what happend you all can't find the answer?

use the potential energy formula, PE=m*g*h.
you will get mass from there then substitute in the kinetic energy formula, KE=1/2*m*v*v.
you have the mass now you can find the velocity.
