Answer:
2.Kinetic energy = 16 Joule
3.H=45m
m=4kg
potential energy (pE)=mgH
P.E=4×9.8×45=1764kgm³/sec²=1764Nm=1764J

Answer:2)=16000
3)=1800000
Explanation:
Question 2:
Mass m=2kg=2000g
Velocity v=4m/s
Kinetic energy==(2000x4x4)/2=2000x4x2=16000
Question :
Mass m =4kg=4000g
Height h=45m
g=10(9.8)
Potential energy=mgh
=4000x10x45=180000
