Answer 2

Given :

• Initial Velocity (u) = 0 m/s

• Acceleration (a) = 2 cm/s²

• Time taken (t) = 3 seconds

To Find :

• Final Velocity = ?

Answer:

By using first equation of motion we get :]

➠ v = u + at

➠ v = 0 + 2 × 3

➠ v = 6 cm/s

Converting cm/s in m/s we get :]

➠ v = 6/100 cm/s

➠ v = 0.06 m/s

Therefore, the Final Velocity of a trolley starting from rest having acceleration 2 cm/s² in time 3 seconds will be 0.06 m/s.

Hope it helps :)
