    ans.:-

    Spead of car after 10 sec.

    v = u + at

    = 0 + 3× 10

    = 30 m/sec.

    = 30× 3600/1000 km/hr.

    = 10.8 km/h

    distance travelled during 10 sec.

    s = ut + 1/2 at^2

    = 0 × 10 + 1/2 × 3 × 10^2

    = 1/2 × 300

    = 150 m

    = 150 × 0.001 hr.

    = 0.150 hr.
