Question

the train moving with the velocity 15m/s is accelerated so that its velocity becomes 20 m/s in 15s. Calculate acceleration of the train​

Answer 1

Answer:

a = 0.3333 m/s²

Explanation:

To calculate acceleration by given values , we can use the formula of -

a = (v_f - v_i) / Δt

where,

a = acceleration

v_f = final velocity

v_i = initial velocity

Δt = acceleration time

By putting the values , we get

a = 0.3333 m/s²

Answer 2

Answer:

0.33 m/s

Explanation:

initial velocity (u)=15m/s

final velocity (v)=20 m/s

acceleration (a)=?

As we know ,

a=Δv/Δt

=(v-u)/Δt

=(20-15)/(15-0)

=5/15

=1/3

=0.33m/s
