The system shown in figure is released then $a_1$ and $a_2$ is
$a_1 = 0.35 m/s^2 ; a_2 = 4.5 m/s^2$
$a_1 = 3 m/s^2 ; a_2 = 0.5 m/s^2$
$a_1 = 2 m/s^2 ; a_2 = 2 m/s^2$
$a_1 = 0.5 m/s^2 ; a_2 = 3 m/s^2$
$Assertion$ : The magnitude of velocity of two boats relative to river is same. Both boats start simultaneously from same point on one bank may reach opposite bank simultaneously moving along different paths.
$Reason$ : For boats to cross the river in same time. The component of their velocity relative to river in direction normal to flow should be same.
When a train is at rest, rain drops fall vertically. When it moves along east with a velocity equal to that of rain, the rain will appear to fall, for a passenger in the train
A man standing on a road hold his umbrella at $30^° $ with the vertical to keep the rain away. He throws the umbrella and starts running at $10\, km/hr$. He finds that raindrops are hitting his head vertically, the speed of raindrops with respect to the road will be......... $km/hr$
A man goes $10\,km$ downstream in $2\,hrs$ and $30\,km$ upstream in $10\,hrs$ . How much time will be take to swim $40\,km$ in still water........$hrs$
A bus appears to go with a speed of $25 \,km / hr$ to a car driver, driving at the rate $7 \,km / hr$ northwards. If the bus actually travels in east direction, its speed is ......... $km / h$
