141709 A body initially lying at a point \((3,7)\) starts moving with a constant acceleration of \(4 \mathbf{i}\). Its position after 3 seconds is

141710 An object is dropped from a tower \(100 \mathrm{~m}\) high. Another is projected upward with a velocity of \(20 \mathrm{~m} / \mathrm{s}\). The time taken for them to collide is

141711 Consider that a truck is moving initially with \(54 \mathrm{~km} / \mathrm{h}\). It has stopped by the driver after looking at an obstacle with a deceleration of 10 \(\mathrm{m} / \mathrm{s}^{2}\). The distance travelled by truck before coming to rest is

141712 The following figure shows the speed-time graph of a particle moving along a fixed direction. The distance travelled by the particle between time \(t=0 s\) to \(t=6 s\) is

141713 The position of an object moving along \(x\)-axis is given as \(\mathbf{x}=\mathbf{a}+\mathbf{b t}^{2}\), where \(\mathbf{a}, \mathbf{b}\) are constants and \(t\) is time in seconds. The object covers a distance of \(16 \mathrm{~m}\) in 2 secs. If the average velocity of the object between \(t=3\) and \(t=5 \mathrm{~s}\) is \(28 \mathrm{~m} / \mathrm{s}\). the values of \(a\) and \(b\) are :
