MOTION IN A STRIGHT LINE

269749 A bullet moving at\(20 \mathrm{~m} / \mathrm{sec}\). It strikes a wooden plank and penetrates \(4 \mathrm{~cm}\) before coming to stop. The timetaken to stop is

1 \(0.008 \mathrm{sec}\)
2 \(0.016 \mathrm{sec}\)
3 \(0.004 \mathrm{sec}\)
4 \(0.002 \mathrm{sec}\)

269750 An automobile travelling with a speed of\(60 \mathrm{~km} / \mathrm{h}\) can brake to stop within a distance of \(20 \mathrm{~m}\). If the car is going twice as fast i.e., \(120 \mathrm{~km} / \mathrm{h}\) the stopping distance will be

1 \(20 \mathrm{~m}\)
2 \(40 \mathrm{~m}\)
3 \(60 \mathrm{~m}\)
4 \(80 \mathrm{~m}\)
MOTION IN A STRIGHT LINE

269751 Apoliceparty is moving in a jeep at a constant speed v. They saw a thief at a distance \(x\) on a motorcycle which is at rest. The moment the police saw the thief, the thief started at constant acceleration \(\alpha\). Which of the following relations is true if the police is able to catch the thief? [2011-E]

1 \(v^{2}<\alpha x\)
2 \(v^{2}<2 \alpha x\)
3 \(v^{2}\lt 2 \alpha x\)
4 \(v^{2}=\alpha x\)
MOTION IN A STRIGHT LINE

269752 Velocity of a body moving with uniform acceleration of\(3 \mathrm{~m} / \mathrm{s}^{2}\) is changed through \(30 \mathrm{~m} / \mathrm{s}\) in certain time. Average velocity of body during this time is \(30 \mathrm{~m} / \mathrm{s}\). Distance covered by it during this time is

1 \(300 \mathrm{~m}\)
2 \(200 \mathrm{~m}\)
3 \(400 \mathrm{~m}\)
4 \(250 \mathrm{~m}\)
