Question

a car accelerate uniformly from 18 km/h to 36 km/h in 2 seconds calculate the acceleration​

Answer 1

Answer:

The acceleration of the car is 900m/s.

Step-by-step explanation:

As the car is accelerating from 1800m/s to 3600m/s in two seconds

you can use the formula a=v-u/t

Answer 2

Answer:

answer is 2.5 m/s

Step-by-step explanation:

initial velocity=u=18km/h

final velocity=v=36km/h

time taken=2 seconds

convert initial and final velocity into m/s

u=18km/h=18x5/18m/s

=5m/s

v=36km/h=36x5/18

=10m/s

a=v-u/t

so,10-5/2

=5/2

=2.5m/s^2

Therefore acceleration is 2.5m/s^2.
