Question

a train starting from rest attains a velocity of 20m/s in 2 minutes. assuming that the acceleration is uniform, find (1) the acceleration (2) distance

Answer 1

Answer:

0.17m/s², 240m

Explanation:

Initial velocity(u) = 0(body starts from rest)

Final Velocity(v)= 20m/s

Time = 2 minutes

        = 120 seconds

(1) - Acceleration = v-u/t

20-0/120 = 1/6 = 0.17m/s²  

(2) - Distance = Velocity * Time

= 20m/s * 120s

=240m

I hope this answer helps you sir.
