ACCELERATION
MOTION IN A STRIGHT LINE

269727 A bus accelerates uniformly from rest and acquires a speed of\(36 \mathrm{kmph}\) in \(10 \mathrm{~s}\). The acceleration is

1 \(1 \mathrm{~m} / \mathrm{s}^{2}\)
2 \(2 \mathrm{~m} / \mathrm{s}^{2}\)
3 \(1 / 2 \mathrm{~m} / \mathrm{s}^{2}\)
4 \(3 \mathrm{~m} / \mathrm{s}^{2}\)
MOTION IN A STRIGHT LINE

269728 Speeds of two identical cars are\(U\) and \(4 U\) at a specific instant. The ratio of the respective distances in which the two cars are stopped from that instant is

1 \(1: 1\)
2 \(1: 4\)
3 \(1: 8\)
4 \(1: 16\)
MOTION IN A STRIGHT LINE

269747 Astartsfrom rest and moves with acceleration \(a_{1}\). Two seconds later, \(B\) starts from rest and moves with an acceleration \(a_{2}\). If the displacement of \(\mathrm{A}\) in the \(5^{\text {th }}\) second is the same as that of \(B\) in the same interval, the ratio of \(\mathrm{a}_{1}\) to \(\mathrm{a}_{2}\) is

1 \(9: 5\)
2 \(5: 9\)
3 \(1: 1\)
4 \(1: 3\)
MOTION IN A STRIGHT LINE

269748 A body travels\(200 \mathrm{~cm}\) in thefirst two seconds and \(220 \mathrm{~cm}\) in the next 4 seconds with deceleration. The velocity of the body at the end of the \(7^{\text {th }}\) second is

1 \(20 \mathrm{~cm} / \mathrm{s}\)
2 \(15 \mathrm{~cm} / \mathrm{s}\)
3 \(10 \mathrm{~cm} / \mathrm{s}\)
4 \(0 \mathrm{~cm} / \mathrm{s}\)
