269706 If a body travels\(30 \mathrm{~m}\) in an interval of \(2 \mathrm{~s}\) and \(50 \mathrm{~m}\) in the next interval of \(2 \mathrm{~s}\), then the acceleration of the body is

1 \(10 \mathrm{~m} / \mathrm{s}^{2}\)
2 \(5 \mathrm{~m} / \mathrm{s}^{2}\)
3 \(20 \mathrm{~m} / \mathrm{s}^{2}\)

269666 If a body starts from rest, then the time in which it covers a particular displacement with uniform acceleration is

1 inversely proportional to the squareroot of the displacement
2 inversely proportional to the displacement
3 directly proportional to the displacement
4 directly proportional to the square root of the displacement
