Question

A car travels at a speed of 50 km/h and accelerates for 45 seconds until it reaches a speed of 95 km/h. What was its acceleration?

Answer 1

Below

Step-by-step explanation:

To find the acceleration of an object you can use this formula :

Vfinal = Vinitial + (acceleration)(time)

I converted everything to m/s then plugged in the values

26.3889m/s = 13.8889m/s + (acceleration)(45s)

acceleration = 0.278 m/s^2

Therefore the acceleration of the car is 0.289 m/s^2

Hope this helps! Best of luck <3
