A) exponential
B) linear
C) second degree
D) non-linear
Correct Answer: B
Solution :
Given, \[F\propto \frac{1}{v}\] \[\Rightarrow \] \[F=\frac{A}{v}\] where A is a constant of integration \[\Rightarrow \] \[m\frac{dv}{dt}=\frac{A}{v}\] \[\Rightarrow \] \[m\int{vdv=A\int{dt}}\] \[\Rightarrow \] \[m\frac{{{v}^{2}}}{2}=At+c,\] Hence, options [b] is correct.You need to login to perform this action.
