Question

a car is travelling at 20 kilometre per hour at speed of 60 kilometre per hour in 6 seconds what is its acceleration​

Answer 1

Answer:

1.85 m/s^2

Explanation:

Given,

u=20 km/h convert into m/s by multiplying 5/18.

=20×5/18

=5.5 m/s

v=60 km/h convert into m/s by multiplying 5/18.

=60×5/18

=16.6 m/s

t=6 s

Now, acceleration =v-u/t

=16.6-5.5/6

=11.1/6

=1.85 m/s^2 is your answer.

Hope it helps you!
