Question

Find velocity v(t) if the rod’s initial velocity was $v_0$ and mass is m.

• A. $v=v_0$
• B. $v=v_0\frac{B^2{l}^{2}v}{mR}t$
• C. $v=v_0{e}^{-\left(\frac{B^2{l}^{2}t}{mR}\right)}$
• D. $v=v_0+\frac{B^2{l}^{2}v}{mR}t$

Answer 1

The correct option is C $v=v_0{e}^{-\left(\frac{B^2{l}^{2}t}{mR}\right)}$
