A) \[1:2\]
B) \[2:1\]
C) (c)\[\sqrt{2}:1\]
D) \[1:\sqrt{2}\]
Correct Answer: A
Solution :
[a] \[S=\frac{{{V}^{2}}-{{U}^{2}}}{2a}\text{ and }a=F/m,\text{ so}\] \[\frac{{{S}_{1}}}{{{S}_{2}}}=\frac{\left( \frac{0-{{U}^{2}}}{2F/m} \right)}{\left( \frac{0-{{U}^{2}}}{2F/2m} \right)}=1.2\]You need to login to perform this action.
