An object is moving with a velocity of 5m-1. At what height must a similar body be situated to have a potential energy equal in value with kinetic energy of the moving body?
A
25.0m
B
20.0m
C
1.3m
D
1.0m
correct option: c
P.E = K.E
Therefore, h = (\frac{v^2}{2g} = \frac{5^2}{2 \times 10})
= 1.25
Approx 1.3 (C)
