A) \[-0.1\times (40)-0.1\times (30)\]
B) \[0.1\times (40)-0.1\times (-30)\]
C) \[0.1\times (40)+0.1\times (-30)\]
D) \[0.1\times (40)-0.1\times (20)\]
Correct Answer: B
Solution :
Impulse = change in momentum \[m{{v}_{2}}-m{{v}_{1}}\]= \[0.1\times 40-0.1\times (-30)\]You need to login to perform this action.
