PHXI03:MOTION IN A STRAIGHT LINE

362349 A ball is dropped from a height of 19.6 \(m\) . The distance covered by it in the last second is

1 19.6 \(m\)
2 14.7 \(m\)
3 4.8 \(m\)
4 9.8 \(m\)
PHXI03:MOTION IN A STRAIGHT LINE

362350 A parachutist after bailing out falls \(50\;m\) without friction. When parachute opens, it decelerates at \(2\;m{s^{ - 2}}\). He reaches the ground with a speed of \(3\;m{s^{ - 1}}\). At what height, did he bail out?

1 \(91\;m\)
2 \(182\;m\)
3 \(293\;m\)
4 \(111\;m\)
PHXI03:MOTION IN A STRAIGHT LINE

362351 Two balls are dropped from same height at 1 second interval of time. The separation between the two balls after 4 second of the drop of the \(1^{\text {st }}\) ball is:

1 \(30\;\,m\)
2 \(35\;\,m\)
3 \(40\;\,m\)
4 \(48\;\,m\)
PHXI03:MOTION IN A STRAIGHT LINE

362352 Assertion :
Two balls of different masses are thrown vertically upward with same speed. They will pass through their point of projection in the downward direction with the same speed.
Reason :
The maximum height and downward velocity attained at the point of projection are independent of the mass of ball.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
