Question

A car goes from 0 to 100 km/hr in 10 seconds. What is its acceleration

Answer 1

a= 2.7 m/s^2

Step-by-step explanation:

acceleration: a

speed: V

Vf = final speed

Vi= initial speed (initial = beginning)

100 km/hour --> m/s

divide the speed value by 3.6

100/3.6= 27.8 m/s

`a = (final speed - initialspeed)/(time)`

`a= (Vf - Vi)/(t) \\`

`a= (27-0)/(10)`

`a= (27)/(10)`

a= 2.7 m/s^2
