Motion in One Dimensions

141911 A body falling from rest has a velocity \(v\) after it falls through a distance \(h\). The distance it has to fall down further, for its velocity to become double, is times \(h\).

1 \(5 \mathrm{~h}\)
2 \(\mathrm{h}\)
3 \(2 \mathrm{~h}\)
4 \(3 \mathrm{~h}\)
Motion in One Dimensions

141912 A wooden block is dropped from the top of a cliff \(100 \mathrm{~m}\) high. Simultaneously a bullet of mass \(10 \mathrm{~g}\) is fired from the foot of the cliff upwards with a velocity of \(100 \mathrm{~ms}^{-1}\). The bullet and wooden block will meet each other after a time

1 \(10 \mathrm{~s}\)
2 \(0.5 \mathrm{~s}\)
3 \(1 \mathrm{~s}\)
4 \(7 \mathrm{~s}\)
Motion in One Dimensions

141913 A ball is thrown vertically up with a velocity of \(4.9 \mathrm{~m} / \mathrm{s}\). The ball is then collected by the person on ground after a time interval of

1 \(3.0 \mathrm{~s}\)
2 \(2.0 \mathrm{~s}\)
3 \(1.0 \mathrm{~s}\)
4 \(0.5 \mathrm{~s}\)
Motion in One Dimensions

141914 A ball which is at rest is dropped from a height \(h\) meter. As it bounces off the floor its speed is \(\mathbf{8 0 \%}\) of what is was just before touching the ground. The ball will then rise to nearly a height:

1 \(0.94 \mathrm{~h}\)
2 \(0.80 \mathrm{~h}\)
3 \(0.75 \mathrm{~h}\)
4 \(0.64 \mathrm{~h}\)
5 \(0.50 \mathrm{~h}\)
