A) \[3V\cos \theta \]
B) \[2V\cos \theta \]
C) \[\frac{3}{2}V\cos \theta \]
D) \[\sqrt{\frac{3}{2}}V\cos \theta \]
Correct Answer: A
Solution :
At the highest point, there is only the horizontal velocity. For conservation of linear momentum \[2m(V\cos \theta )\,=V'-mV\,\cos \theta \] \[V'=3\,V\cos \,\theta \]You need to login to perform this action.
