Question

an object of mass 40 kg is raised to a height of 5m above the ground ...what is its potential energy?If the object is allowed to fall ..find its kinetic energy when it is half way down.....
plz answer fast.......​

Answer 1

potential energy =mgh

=40*9.8*5= 1960 kgm^2/s^2.

Kinetic energy= 1/2 mv^2..

but you have not mentioned velocity.. I am leaving velocity.. You can put the value in it..

1/2* 40* v^2= 20v^2..

hope it helps you..
