H=45m
m=4kg
potential energy (pE)=mgH
P.E=4×9.8×45=1764kgm³/sec²=1764Nm=1764J
m=4kg
potential energy (pE)=mgH
P.E=4×9.8×45=1764kgm³/sec²=1764Nm=1764J

given: mass=4kg, height=45m and considering g=10m/s^2
since,P.E.=mgh
therefore,P.E.=4×10×45
P.E.=1800
since,P.E.=mgh
therefore,P.E.=4×10×45
P.E.=1800
