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 \[=20\,m\text{/}{{s}^{2}},\] \[dt=0.1\,s\] Force, \[F=ma=0.15\times 20=3N\] Now impulsive force \[=F\times dt=3\times 0.1\] \[=0.3\,Ns\]You need to login to perform this action.
