Question

velocity of a train increases to 60 km/h from 45km/h in 10 minutes.Find the acceleration in the train​

Answer 1

Answer:

Hope the answer attached would help

Explanation:

the quantities are solved using SI units.

Happy learning :))

sorry the answer would be +25m/s i mistakenly took the initial velocity as final velocity

Answer 2

Initial velocity (u) = 45 km/h

Final velocity (v) = 60 km/h

Time taken to change the velocity (t) = 10 minutes = 1/6 hour

We know,

a = (v - u)/t

• a = Acceleration,
• v = Final velocity,
• u = Initial velocity and
• t = Time taken.

Hence,

a = (60 km/h - 45 km/h)/(1/6 h)

⟹ a = (15 km/h)/(1/6 h)

⟹ a = (15 km/h × 6)/h

⟹ a = 90 km/h² (Solution)

To convert the acceleration into (m/s²), convert the velocities into (m/s) and the time taken in (s). Then, put the values according to the formula.
