A group of students is investigating how a force applied to an object affects the motion of that object. The diagram shows the setup of the investigation. To create a force, the students add a weight to the weight holder and observe whether or not the cart moves. The students repeat this step five times, using a different amount of weight each time. Make a claim about the forces acting on the cart when the cart does not move.

While strolling downtown on a saturday afternoon, you stumble across an old car show. as you are walking along an alley toward a main street, you glimpse a particularly stylish alpha romeo pass by. tall buildings on either side of the alley obscure your view, so you see the car only as it passes between the buildings. thinking back to your physics class, you realize that you can calculate the car's acceleration. you estimate the width of the alleyway between the two buildings to be 6 m. the car was in view for 0.6 s. you also heard the engine rev when the car started from a red light, so you know the alpha romeo started from rest 4 s before you first saw it. find the magnitude of its acceleration.
