Answer:
1.8 seconds
Explanation:
- Initial velocity (u) = 0 m/s
[Since, it is at rest. ]
- Acceleration (a) = 0.0075 m/s²
- Final velocity (v) = 0.0135 m/s²
We are asked to calculate time taken to reach a speed of 0.0135m/s.
By using the first equation of motion,
→ v = u + at
- v denotes final velocity
- u denotes initial velocity
- a denotes acceleration
- t denotes time taken
Substituting values,
→ 0.0135 = 0 + 0.0075t
→ 0.0135 = 0.0075t
→ 0.0135 ÷ 0.0075 = t
→ 1350000 ÷ 750000 = t
→ 135 ÷ 75 = t
→ 1.8 = t
→ Time taken = 1.8 seconds
Therefore, it takes 1.8 seconds to reach a speed of 0.0135m/s.
