Question

Acar start from rest and go with velocity of 4m/s for 4second what is acceleration of car​

Answer 1

Answer:

1m/s

Explanation:

Given

initial velocity(u)=0

final velocity(v)=4m/s

timetaken (t)=4

Aceleration(a)=v-u÷t

now

=4-0÷4

=1m/s

Answer 2

Answer:

1 m/s^2

Explanation:

The formula for accleration is a=Δv/Δt

where, Δv = final velocity - initial velocity = 4 - 0 = 4

initial velocity = 0 since the car starts form rest and final velovity is 4 as the car goes from rest till 4 m/s

Δt = 4 since the car takes 4 seconds to reach a velocity of 4m/s

Hence, a = 4 m/s / 4 s = 1 m/s^2
