A car is pushed along by the road with 4000 N of force so that it accelerates at 2m/s squared. What is the mass of the car?
plz explain

F=m*a
4000=2*m
m=2000 kg

Use the formula F = ma. F is 4000 N, a is 2 m/s^2. Solve for m by dividing F by a. m will be in kg.

This is trivial. It's a problem that is used to remember the formula for the second Newton's Law (don't forget this one if you want to pass any physics exam!):
F = m*a => m = F/a = (4000 N)/(2 m/s^2) = 2000 kg

F=ma
4000N=m(2m/s^2)
m=2000kg

Newton's second law
F=m*a;
mass m=4000 / 2=2000 kg

F=ma
you fill in what you know.
4000N=m * 2m/s
then you see that you know the total but not the mass
so you rearrange the problem by dividing by 2m/s on each side.
it cancels out on the side of the mass and on the side of the newtons it becomes 4000N divided by 2m/s
your answer is m = 2000kg
