Question

A car accelerates from 18 km/h to 36km/h in 20 seconds uniformly, its acceleration will be? Plz answer!

Answer 1

Explanation:

⇒ a = 1 m/s². Hence, the acceleration of the car is 1 m/s². ⇒ s = 37.5 m

Answer 2

Answer:

2.5m/s^2

Explanation:

change km/h into m/s = 18km=18000m/1h=3600s  =5m/s

                                     36km=36000m/1hr =3600s =10m/s

acceleration =v-u/t

                    u =intial velocity, [5m/s]

                    v =final velocity,[10m/s]

                    t =time taken, [20s]

10m/s-5m/s divide 20s=2.5m/s^2
