1. A vehicle travels half the distance with speed q and the 5. Preeti reached the metro station and found that the escalator
remaining distance with speed 2q. Its average speed is: was not working. She walked up the stationary escalator
(2023) in time t1. On other days, if she remains stationary on the
moving escalator, then the escalator takes her up in time t2.
3q q 2q 4q
(1) (2) (3) (4) The time taken by her to walk up on the moving escalator
4 3 3 3 will be: (2017-Delhi)
2. The ratio of the distance traveled by a freely falling body in t1t 2 t1t 2
(1) (2) (3) t2 – t1 (4) t1 + t 2
the 1st, 2nd, 3rd and 4th second : (2022) t 2 − t1 t 2 + t1 2
(1) 1 : 1 : 1 : 1 (2) 1 : 2 : 3 : 4 6. The ‘x’ and ‘y’ coordinates of the particle at any time are
(3) 1 : 4 : 9 : 16 (4) 1 : 3 : 5 : 7 ‘x’ = 5t – 2t2 and ‘y’ = 10t, respectively, where ‘x’ and ‘y’ are
3. The displacement time graphs of two moving particle make in metres and ‘t’ in seconds. The acceleration of the particle
angles of 30° and 45° with the x-axis as shown in the figure. at t = 2 s is: (2017-Delhi)
(1) 5 m/s 2 2
(2) –4 m/s (3) –8 m/s (4) 0 2
The ratio of their respective velocity is : (2022)
7. Two cars P and Q start from a point at the same time
in a straight line and their positions are represented by
XP(t) = at + bt2 and XQ(t) = ft – t2. At what time do the cars
displacement
(3) 2 m/s, 4 m/s (4) 1·5 m/s, 3 m/s (3) –2nβ e 2 –4n + 1 (4) –2nβ2 x–2n – 1
