MOTION IN A STRIGHT LINE

269762 A boy throws\(n\) balls per second at regular time intervals. When the first ball reaches the maximum height he throws the second one vertically up. The maximum height reached by each ball is

1 \(\frac{g}{2(n-1)^{2}}\)
2 \(\frac{g}{2 n^{2}}\)
3 \(\frac{g}{n^{2}}\)
4 \(\frac{g}{n}\)

269763 A body is thrown vertically upward from a point '\(A\) ' \(125 m\) above the ground. It goes up to a maximum height of \(250 \mathrm{~m}\) above the ground and passes through ' \(A\) ' on its downward journey. Thevelocity of the body when it is at a height of \(70 \mathrm{~m}\) above theground is \(\left(\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}\right)\) (MED-2013)

1 \(20 \mathrm{~m} / \mathrm{s}\)
2 \(50 \mathrm{~m} / \mathrm{s}\)
3 \(60 \mathrm{~m} / \mathrm{s}\)
4 \(80 \mathrm{~m} / \mathrm{s}\)

269764 A body is released from the top of a tower of height\(\mathrm{H} \mathrm{m}\). After \(2 s\) it is stopped and then instantaneously released. What will be its height after next \(2 \mathrm{~s}\) (in metres)?

1 \(\mathrm{H}-5\)
2 \(\mathrm{H}-10\)
3 \(\mathrm{H}-20\)
4 \(\mathrm{H}-40\)
