A race car has a mass of 710 kg. It starts from rest and reaches a final speed of 12.0 m/s in 3 seconds. If the car is
uniformly accelerating during the entire time, what is the net force acting on it?
A :-) for this question , first we should find acceleration - a = v - u by t Given - u = 0 m/s v = 12 m/s t = 3 sec Solution - a = v - u by t a = 12 - 0 by 3 a = 12 by 3 a = 4
