Question

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

Answer 1

Answer:

a= 2.7 m/s^2

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

$a = \frac{final speed - initialspeed}{time}$

$a= \frac{Vf - Vi}{t}$

$a= \frac{27-0}{10}$

$a= \frac{27}{10}$

a= 2.7 m/s^2
