its been a year now i'm back . help plz ? =D hey guys it's been a while i haven't been on in a long time since last year when i last had physics 10 the introductory course and now i'm back just looking for guidance how to do this question ( helping friend :!!) anyways here it is: A racing car has a mass of 1500kg, is accelerating at 5.0m/s^2, is experiencing a lift force of 600 N up (due to its streamlined shape) and ground effects of 1000 N down (due to air dams and spoilers). Find the driving force needed to keep the car going given that uk = 1.0 for the car since it's been so long since i've last done physics the only equation that comes to mind is Fnet = ma but i'm sure that's wrong lol sooo can someone help me out? thanks !
