Answer 1

GiveN :

• Initial velocity (u) = 0 m/s
• Acceleration = 0.2 m/s²
• Time = 3 mins = 3*60 = 120s

To FinD :

• Final Velocity

SolutioN :

Use 1st equation of motion :

⇒v = u + at

⇒v = 0 + 0.2 * 120

⇒v = 24 m/s

Answer 2

acceleration = velocity / time

0.2 = velocity/ 3× 60

0.2 = velocity/ 180

0.2 × 180 = velocity

velocity = 36 m/s
