An object of mass 200kG is at a height of 50 meters above the ground and is moving with a speed of 1.8m⁄s . Calculate its:
- Potential energy at that height?
- Kinetic energy?
- Total energy and momentum?
- Objects total momentum at that height?
Potential energy at that height = mgh
= 200 * 9.8 * 50
= 98000 J
Kinetic energy = 1/2mv2
= 1/2 * 200 * 1.82
= 324 J
Total energy = 98000 + 324
= 98324 J
Objects total momentum at that height = mv
= 200 * 1.8
= 360 kg.m/s
