Question

A body is thrown up with a kinetic energy of 100J find the maximum hight obtained by the object if its mass is 1 kg​

Answer 1

$10 \: m$

Explanation:

$Given, \: E=100J, \: m=1 \: kg \: \: \: and \: \: \: h= ? \\ At \: \: a \: \: height \: \: h \: \: the \: \: kinetic \: \: energy \: \: of \: \: \\ the \: \: object \: \: is \: \: converted \: \: into \: \: potential \: \: energy \\ then, \: \: \: \: \boxed{E = mgh} \\ Now, \: \: \: \: \: 100 = 1 \times 10 \times h \\ \: \: \: \: \: \: \: \: \: \: \: \: \: h = \frac{100}{10} \: m \\ \: \: \: \: \: \: \: \: \: \: h = 10 \: m$

Answer 2

Explanation:

a body of mass 10 kg falling frely on groundtop to lower to hight find k .e
