Explanation:
Detailed explanation-1: -Answer: From formula point of view, potential energy is mass*gravity*height so accordingly here PE = 2*10*20 (for calculation part, we take g approx 10 actual being 9.8), so PE = 400Joule.
Detailed explanation-2: -V = SQRT (PE*2 / m) Variables: Where V is the Velocity from Potential Energy (m/s) PE is the total potential energy (J) m is the mass of the object (kg)
