A ball of mass 10 g falls from a height of 5 m. It rebounds from the ground to a height of 4 m. (take g=10 m/s) Find: (i) the initial potential energy of the ball. 0.5 Joule (ii) the kinetic energy of the ball just before striking the ground. 0.5 Joule (iii) the kinetic energy of the ball after striking the ground. ??? (iv) the loss in kinetic energy of the ball on striking the ground. 0.1 Joule

Ok so if anyone is so kind enough to tell me when to convert kgf to N or even when g= 10m/s^2 is given, when should we convert. and is it necessary to convert to g from kg when solving for the Work done (Kinetic or potential energy.) I know its a silly doubt, but please help me.

Critical angle for diamond is 24 degrees.Explain the statement

in this question
A man having a box in head climbs a slope and another man  having an identical box walks the same distance on a levelled road.Who does more work against the force of gravity and why?
why everyone is concluding that the work in 2 case is zero.
is it not possible that the man is pushing the box on the road for causing displacement ??????
