distance = 460
Explanation:
vilocity (U) = 20 m/s
- accelerating =0.5m/s2
- Time = 30s
- we have to find distance , we apply 2nd equation of vilocity time graph
- s = 1/2u + at2 by this formula we obtain distance
- s = distance
- u = intial vilocity
- a = acceleration
- t = time
s = 1/2×20 + 0.5×(30)2
s = 10 + 5/10 × 900
s = 10 + 450
s = 460 km /h
