An oscillating pendulum has a velocity of 2ms-1 at the equilibrium position O and velocity at same point P. Using the diagram above, calculate the height of P above O. (Take g = 10ms2)
- 5.0m
- 2.0m
- 0.4m
-
0.2m
- 0.1m
The correct answer is: D
Explanation
Kinetic energy at O = P.E at P 1/2mV = mghh = v/2g = 0.2m
