146052 A car of mass \(m\) is driven with an acceleration a along a straight level road against a constant external resistive force \(R\). When the velocity of the car is \(v\), the rate at which engine of the car is doing work will be

1 R.v
2 ma.v
3 \((\mathrm{R}+\mathrm{ma}) \cdot \mathrm{v}\)
4 \((\mathrm{ma}-\mathrm{R}) . \mathrm{v}\)

146053 Two unequal masses are connected on two sides of a light string passing over a light and smooth pulley as shown in the figure. The system is released from the rest. The larger mass is stopped for a moment, \(1 \mathrm{~s}\) after the system is set into motion and then released immediately. The time elapsed before the strings is tight again is

1 \(1 / 4 \mathrm{~s}\)
2 \(1 / 2 \mathrm{~s}\)
3 \(2 / 3 \mathrm{~s}\)
4 \(1 / 3 \mathrm{~s}\)
