Question

a body of mass 2 kg is thrown vertically upward with kinetic energy 245 J. The acceleration due to gravity is 9.8m/s^2 the kinetic energy of the body will become half at a hieght of

Answer 1

total energy launch=total energy later

245J=KE(h) + PE(h)
= 245/2+mgh

h= 245/(2*2*9.8) meters

Answer 2

I need a solution
