A) \[\frac{m\upsilon }{2}\]
B) \[\frac{\sqrt{3}m\upsilon }{2}\]
C) \[m\upsilon \]
D) \[\frac{\sqrt{7}m\upsilon }{2}\]
Correct Answer: B
Solution :
At point O, \[=V\,\cos \theta i+V\sin \theta j\] at point O: \[\therefore \] \[{{V}_{f}}=u\,\cos \theta i=\Delta P\,m({{V}_{f}}-{{V}_{i}})\] \[\Delta P=-m\upsilon \,\sin \theta j\] \[|\Delta P|=m\upsilon \,\sin {{60}^{o}}=\frac{\sqrt{3m\upsilon }}{2}\]You need to login to perform this action.
