Answer:
see,
for 1st column
in these quetions mass and height is given. value of g (acceleration due to gravity) is always constant, that is 9.8 but it is given in the quetion to take g as 10
we have a formula to find out the potential energy. that is...mgh
so, in these quetions potential energy of object can be found by simply multiplying them.
for 2nd column
we have a formula to find out the kinetic energy of an object which is mv²/2
m= mass, v= velocity.
so again put the value...

i hope you got the point
