The velocity of a particle is \(v=v_0+g t+{Ft}^2.\) Its position is \(x = 0\) at \(t = 0,\) then its displacement after time \((t = 1)\) is:
1. \(v_0+\frac{g}{2}+\frac{F}{3}\)
2. \(v_0+\frac{g}{2}+F\)
3. \(v_0+2 g+3 F\)
4. \(v_0+g+F\)

A boy reaches the airport and finds that the escalator is not working. He walks up the stationary escalator in time \({t}_1 .\) If he remains stationary on a moving escalator then the escalator takes him up in time \({t}_2 .\) The time taken by him to walk up on the moving escalator will be:
1. \(\dfrac{t_1 t_2}{t_2+t_1}\)
2. \({t}_2\text-{t}_1\)
3. \(\dfrac{t_1+t_2}{2}\)
4. \(\dfrac{t_1 t_2}{t_2-t_1}\)

1. \(1\) drop /\(7\) seconds
2. \(3\) drops /\(2\) seconds
3. \(1\) drop / second
4. \(2\) drops / second

A balloon was moving upwards with a uniform velocity of \(10~\text{m/s.}\) An object of finite mass is dropped from the balloon when it was at a height of \(75 ~\text{m}\) from the ground level. The height of the balloon from the ground when the object strikes the ground will be:
(takes the value of \(g\) as \(\mathrm{10 m /s^2}\))
1. \(250~\text{m}\)
2. \(300~\text{m}\)
3. \(200~\text{m}\)

Water drops are falling from the nozzle of a shower onto the floor, from a height of \(9.8~\text{m.}\) The drops fall at regular intervals of time. When the first drop strikes the floor, at that instant, the third drop begins to fall. Then the position of the second drop from the floor when the first drop strikes the floor is:
1. \(4.18~ \text{m}\)
2. \(2.94~ \text{m}\)
3. \(2.45~ \text{m}\)
4. \(7.35~ \text{m}\)
