A) 24.5 N-s
B) 49.0 N-s
C) 98.0 N-s
D) 50.0 N-s
Correct Answer: A
Solution :
Initial momentum \[=mu=0\] Final momentum = m (Horizontal component of velocity) \[=m(v\,\,\cos \theta )\] \[=0.5\times 98\times \cos \,\,60\] \[=24.5N\text{-s}\] \[\therefore \] Change in momentum \[=24.5-0\] \[=24.5N\text{-s}\]You need to login to perform this action.
