1.	a train is moving with velocity 30 metre per second comes to rest after covering a distance of 2800 metre calculate its acceleration
Answer» Answer: -0.16 m/s Explanation: Use EQUATION of motion a = (v² - u²) / (2S) = (0² - 30²) / (2 × 2800) = -900/5600 m/s² = -0.16 m/s Negative SIGN indicates that it's RETARDATION.

Answer»

Answer:

-0.16 m/s

Explanation:

Use EQUATION of motion

a = (v² - u²) / (2S)

= (0² - 30²) / (2 × 2800)

= -900/5600 m/s²

= -0.16 m/s

Negative SIGN indicates that it's RETARDATION.
