Question
A car starts moving with constant acceleration covers the distance between two points 180 meters apart in 6 seconds. Its speed as it passes the second point is 45 m/s. Find its speed when it was at the first point.
- 15 m/s2
- 15 m/s
- 10 m/s
- 5 m/s
The correct answer is: 15 m/s
From (1)
u = 45 - 5 ´ 6 = 15 m/s.
