1.	A trolley, while going down an inclined plane, has an acceleration of 2 cm/s2 . What will be its velocity 3 s after the start?
Answer» Here we have, Initial velocity, u = 0 m/s Acceleration (a) = 2 cm/s² = 0.02 m/s² Time (t) = 3 s Final velocity, v = ? We know that, v = u + at Therefore, v = 0 + 0.02 × 3 m/s ⇒ v = 0.06 m/s Therefore the final velocity of trolley will be 0.06 m/s after start.

Answer»

Here we have,

Initial velocity, u = 0 m/s

Acceleration (a) = 2 cm/s² = 0.02 m/s²

Time (t) = 3 s

Final velocity, v = ?

We know that, v = u + at

Therefore, v = 0 + 0.02 × 3 m/s

⇒ v = 0.06 m/s

Therefore the final velocity of trolley will be 0.06 m/s after start.
