Question

Calculate the acceleration if an engine starts from rest and moves with uniform
acceleration, attaining a speed of 40 km/h in 10 minutes.​

Answer 1

Step-by-step explanation:

Question:-

A train starting from a railway station and moving with uniform acceleration attains a speed of 40 km hr-1 in 10 minutes. Find its acceleration in the units of ms-2.

Answer:-

Given:-

• The speed of the engine = 40 km/h in 10 minutes.

To find:-

• Acceleration of the train.

Solution:-

Initial velocity (u) = 0

Final velocity (v) = 40 km/h

v = 40 × (5/18)

⇢ v = 11.1111 m/s

Time (t) = 10 minute

t = 60 x 10

t = 600 s

Acceleration (a) =?

Consider the formula⇝

⇢ v = u + at

11.11 = 0 + a × 600

11,11 = 600 a

a = 11.11/600

a = 0.0185 ms-2 (Ans)

Answer 2
