Question

A car is travelling at 54 km/hr. If it's velocity increases to 72 km/hr in 5 sec . Find the acceleration of the car in SI units​

Answer 1

Answer:

acceleration is defined as the rate of change of velocity per unit time. so

a=v-u/t

Answer 2

Answer:

1m/s²

Explanation:

initial velocity (u)=54km/hr

                           ⇒54×5/18m/s

                          ⇒3×5 = 15m/s

final velocity (v) =72km/hr

                           ⇒72×5/18m/s

                          ⇒4×5=20m/s

a=v-u/t

                            a=20-15/5

                           ⇒5/5=1m/s²

                          a=1m/s²
