Question

Your car is initially at rest when your hit that gas and the car begins to accelerate. The forward force on the car is 5410 N while the resisting forces total 210 N. The car has a mass of 1504 kg and the acceleration lasts for 6.7 s. What is the final speed of the car and how much ground does it cover during this acceleration

Answer 1

Answer:

Below

Explanation:

First, we have to find the acceleration of the car.

     Fa - Ff = F

     5140 - 210 = 5200 N

     acceleration = Force / mass

     a = 5200 / 1504

     a = 3.4574 m/s^

Now we can use this formula to find the final velocity of the car :

     vf = vi + at

     vf = 0 + (3.4574)(6.7s)

     vf = 23.16 m/s

We need to round this to 2 sig figs :

     vf = 23 m/s

Hope this helps!
