            5.    Two masses m 1 and m 2 are dropped from heights h 1 and h 2. The ratio of time taken by them to fall
                on the Earth’s surface is

                          1/2
                a.  (h 1/h 2)

                Two train 100 m and 50 m in length are running in opposite direction with velocities 40 km/h
                and 20 km/h. The time when they will completely cross each other

                a.  4 s.
                b.  6 s.

                c.  8 s.

                d.  9 s.
            7.    ABCD is a square of side a. A body starts from A and reaches D
                through indicated path. The ratio of displacement to distance
                travelled is
                    a.  ½
                    b.  √2

                A food packet is released from a helicopter rising steadily at the speed of 12 m/s. After 2 seconds
                                                      2
                the velocity of the packet is (g=9.8 m/s )
                a.  –12 m/s.
                b.  -7.6 m/s.

                c.  7.6 m/s.

                d.  12 m/s.

                                                                                           2
                The  position  coordinates  of  a  moving  body  are  given  by  x=4+10t+15t .  The  acceleration
                is (Where x is in meters and t is in seconds.)
                          2

                The velocity-time graph of a body moving in a straight line is shown in figure. The distance and
                displacement             traveled           by            the           body            in
                6 seconds are, respectively:

                    a)  8 m, 8m.
                    b)  16 m, 16 m.
