hey mate please answer✨✨✨✨☺️☺️☺️☺️☺️❤️
A body faaling freely under gravity its velocity is v when it has lost potential energy equal to U what is the mass of the body ??

lost in potential energy = gain in kinetic energy
U = 1/2 . m . V^2
2U/V^2 = MASS
U = 1/2 . m . V^2
2U/V^2 = MASS

hey dear here is ur answer
Mass multiplied by acceleration (9.81m/s) and multiplied by the distance that the body falls. The equation is (m)(g)(h2-h1). In case you haven’t noticed, work done is simply energy x distance traveled. In this problem work done by gravity is also the change in potential energy.
hope it helps u
