Question

A car moving with a velocity of 10m/s¹ and with a uniform accleration gains a velocity of 30m/s¹after travelling a distance of6km.the time taken is

Answer 1

Time = Distance / speed

Speed = change in speed

Change in speed = Final speed - initial speed

Final speed = 30m/s

Initial = 10m/s

Δspeed = 30 - 10 = 20m/s

Distance = 6 × 1000 = 6000m

Time = 6000/20 = 300

= 300 seconds
