Solution,
Here, we have
Initial velocity of the trolley, u = 0 (As starts from rest)
Acceleration of the trolley, a = 0.02 m/s²
Time taken by the trolley, t = 3 seconds
To Find,
Final velocity of the trolley, v = ?
According to the 1st equation of motion,
We know that,
v = u + at
So, putting all the values, we get
⇒ v = u + at
⇒ v = 0 + 0.02 × 3
⇒ v = 0.02 × 3
⇒ v = 0.06 m/s
Hence, the final velocity of the trolley is 0.06 m/s.
