A. 1600 J
B. 900 J
C. 600 J
D. 200 J
Correct Answer:
Option A – 1600 J
A body of mass 2 kg is released from a point 100 m above the ground. Calculate its kinetic energy 80m from the point of release.
![A body of mass 20g projected vertically upwards in vacuum returns to the point of projection after 1.2s. [g = 10ms-2]. Determine the potential energy of the body at the maximum height of its motion.](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png "A body of mass 20g projected vertically upwards in vacuum returns to the point of projection after 1.2s.
