Question

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

v =

Answer 1

Answer:

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

Step-by-step explanation:

Total energy-k.e+p.e

M.E-P.E=K.E

Now,

Now,Solving for velocity

V² =2(M.E-P.E)/m

Therefore,

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