A) \[1m{{s}^{-1}}\]
B) \[4m{{s}^{-1}}\]
C) \[2m{{s}^{-1}}\]
D) \[2\sqrt{2}m{{s}^{-1}}\]
Correct Answer: C
Solution :
From work energy theorem,\[\Delta KE={{W}_{net}}\] \[{{K}_{fi}}-{{K}_{i}}=\int{P}\,\,dt\] \[\frac{1}{2}m{{v}^{2}}-0=\int_{0}^{2}{\left( \frac{3}{2}{{t}^{2}} \right)dt}\] \[\frac{1}{2}(2){{v}^{2}}=\frac{3}{2}\left[ \frac{{{t}^{3}}}{3} \right]_{0}^{2}=4\]You need to login to perform this action.
