B) \[\frac{m{{v}^{2}}}{{{T}^{2}}}{{t}^{2}}\]
C) \[\frac{1}{2}\frac{m{{v}^{2}}}{{{T}^{2}}}{{t}^{2}}\]
D) \[\frac{1}{2}\frac{m{{v}^{2}}}{{{T}^{2}}}{{t}^{2}}\]
Correct Answer: A
Solution :
[a] The force |
Instantaneous power |
(force F and velocity v both are in same direction) |
Instantaneous process delivered in time t |
(from equation of motion,) |
