KE = PE
1/2 mv² = m g h
1/2 x 10 x 1600 x 10 x 10 x h
160/2 = h
80 m = height
1/2 mv² = m g h
1/2 x 10 x 1600 x 10 x 10 x h
160/2 = h
80 m = height

Hey!
v=40m/s
m= 10kg
Taking g= 10m/s
[Answer may varry if g=9.8m/s]
K.E=P.E
1/2mv^2=mgh
1/2×10×(40)^2=10×10×h
5×1600=100×h
8000=100×h
8000/100=h
h=80m
At height of 80m , Kinetic energy= Potential energy.
Hope it helps...!!!
