what you have to do is first draw a table of diff. heights like -:
HEIGHT P.E K.E T.E
1M MGH 1/2 MV^2 P.E+K.E
2M
3M
4M
5M
6M
7M
8M
9M
10M
THEN NOW YOU HAVE TO CALCULATE THE T.E AND LET "G" BE 10m/s^2 and "H" be 1,2,3,4,5,6,7,8,9,10 mrs. and then calculate .
hope you like it and pls mare as brainest
