Accelerating a car at 4.6 m/s. it takes 10 seconds to reach acceleratuon. starting velocity is 0 m/s. what is the final velocity?

I assume you mean the acceleration you want to reach is 4.6 m/s^2, and it takes 10 s linearly to get there.

Then this will be an integration problem, you need to integrate the velocity in form of acceleration with respect to time.

So a = 0.46t, where a is acceleration, t is time

So your velocity at time t equals to: a*t = 0.46t^2

So at t=10, V = 0.46 * 10^2 = 46 m/s

Well the magnitude of its acceleration related to that car starts with the oil change like when you have to change the oil in your car you have to make sure that your precious car is starting really propley and very well
