The string shown in the figure is passing over small smooth pulley rigidly attached to trolley A. Speed of trolley is constant and equal to \(\mathbf{v}_{A}\). Speed and magnitude of acceleration of block B at the instant shown in figure is
- \(v_{B}=v_{A}, a_{B}=0\)
- \(a_{B}=0\)
- \(v_{B}=\frac{3}{5} v_{A}\)
- \(a_{B}=\frac{16 v_{A}^{2}}{125}\)
Answer
(C) v_ B = 3 5 v_ A
