Question

a train starting from railway station attains a speed of 20 m/s in one minute find its acceleration?​

Answer 1

Explanation:

u = 0 m/s

v = 20 m /s

t = 1 min = 60 sec

now,

acceleration = v-u / t

= 20 - 0 / 60

= 20/60

= 0.33333 m/s square

Answer 2

To Find:-

• The acceleration

Given:-

Initial Velocity = 0 m/s

Final Velocity = 20 m/s

Time Taken = 1 minute (1 minute = 60seconds)

Solution:-

here,

Acceleration ( a )

Initial Velocity ( u )

Final Velocity ( v )

Time Taken ( t )

step-by-step explanation:

We know that :-

$a = \dfrac{v - u}{t}$

Putting the values,

$a = \dfrac{20 - 0}{60}$

$a = \dfrac{20}{60}$

a = 0.33 m/s²
