The above free body diagram represents the motion of a toy car across a floor from left to right. the weight of the .5 kg car is about 5 n and it is being pushed with 20 n of pressure. if there is 10 n of friction across the floor, what is the net force acting on the car?
a
since the car is moving to the right, the normal force is balancing the weight and the net force is 10 n, right.
b
friction and the normal force are acting opposite the applied force, so the net force is 5 n, right.
c
the net force is 35 n, the addition of each of the forces acting on the car and causing it to accelerate.
d
net force is equal to mass times acceleration so the net force is .5 kg times 9.8 m/s^2 or roughly 5 n.
