PHXI03:MOTION IN A STRAIGHT LINE

362362 A ball is thrown up under gravity \(\left( {g = 10\,m/{{\sec }^2}} \right)\). Find its velocity after \(1.0\,\sec \) at a height of \(10\,m\).

1 \(5\,m/{\sec ^2}\)
2 \(5\,m/\sec \)
3 \(15\,m/\sec \)
4 \(10\,m/\sec \)

362363 A man standing in a lift falling under gravity releases a ball from his hand. As seen by him, the ball

1 Falls down
2 Remains stationary
3 Goes up
4 Executes SHM
PHXI03:MOTION IN A STRAIGHT LINE

362364 Two bodies of different masses are dropped simultaneously from the top of a tower. If air resistance is proportional to the mass of the body, then,

1 The heavier body reaches the ground earlier
2 The lighter body reaches the ground earlier.
3 Both the bodies reach the ground simultaneously.
4 Cannot be decided.
PHXI03:MOTION IN A STRAIGHT LINE

362365 A body projected vertically upwards with a certain speed from the top of a tower reaches the ground in \(t_{1}\). If it is projected vertically downwards from the same point with the same speed, it reaches the ground in \(t_{2}\). Time required to reach the ground, if it is dropped from the top of the tower, is

1 \(\sqrt{t_{1}+t_{2}}\)
2 \(\sqrt{\dfrac{t_{1}}{t_{2}}}\)
3 \(\sqrt{t_{1}-t_{2}}\)
4 \(\sqrt{t_{1} t_{2}}\)
