A) \[1.5 m/{{s}^{2}}\]
B) \[1.5\,km/{{h}^{2}}\]
C) \[3 m/{{s}^{2}}\]
D) \[3\,\,km/{{h}^{2}}\]
Correct Answer: A
Solution :
Force exerted on block by jet stream, \[F=v\frac{dm}{dt}\]\[=\,\,\,3\,\,\times \,\,2=6\,N\] Now acceleration of block will be, \[a=\frac{F}{m}=\frac{6}{4}\]\[=\,\,\,1.5 m/{{s}^{2}}\]You need to login to perform this action.
