A) \[1.2\,\,Ns\]
B) \[0.3\,\,Ns\]
C) \[0.1\,\,Ns\]
D) \[0.5\,\,Ns\]
Correct Answer: B
Solution :
Here: mass of the ball\[m=150\,\,g\]time\[=0.15\,\,kg\] Acceleration of the ball\[=20m/{{s}^{2}}\] \[dt=0.1\,\,s\] Force, \[F=ma=0.15\times 20=3\,\,N\] Now impulsive force \[=F\times dt=3\times 0.1\] \[=0.3\,\,Ns\]You need to login to perform this action.
