Question

a train starting from a railway station and moving with uniform acceleration attains a speed 40 kilometre per hour -1 in 10 minutes find its acceleration​

Answer 1

Answer:4 km/sec/sec

Explanation: acceleration=final velocity–initial velocity /time

So,

40–0/10

=40/10

=4

Answer 2

Solution:

By applying the formula of acceleration, we get the acceleration.

We know that the rate at which the velocity of an object changes, that is, the change in velocity per unit time, is called acceleration of the object.

Acceleration = Total change in velocity / Total time required for change

We know that, in C.G.S. system unit of acceleration is cm/s^2.

Acceleration = v - u / t

Acceleration = 40 - 0 / 10 × 60

Acceleration = 40 × 1000 × 100 / 3600 × 10 × 60

Acceleration = 1.85 cm/s^2

Thus, its acceleration is 1.85 cm/s^2.
