Question

The total mechanical energy of an object with mass m at height h in a closed system can be written as
`ME = (1)/(2) mv^(2) +mgh`. Solve for v, the velocity of the object, in terms of the given quantities.

v =

Answer 1

v=
`\sqrt2(M.E)/m -gh`

Explanation:

total energy=k.e+p.e

M.E-P.E=K.E

SOLVINGG FOR VELOCITY

`V^(2)`=2(M.E-P.E)/m

v=\sqrt2(M.E)/m -gh
