Question

a car is moving with a initial velocity 10m/s and come to rest the time taken is 1hour find the acceleration​

Answer 1

Explanation:

Here v=0m/sec.

u=10m/sec

time taken=1hr=(60×60)sec =3600sec.

so,

acceleration=v-u =0m/s-10m/s

t 3600s

= -10m/s = 0.00277777778m/s^2

3600s

Answer 2

Explanation:

Final velocity (v) = 0m/s

Initial velocity (u)= 10m/s

Time taken= 1hour or 3600 secs

a= v-u/t

a= 0-10/3600

a= -10/3600 m/s

Hope it helped you dear.
