4. Suppose that a small car pushes on a truck with a stalled engine, as shown in the picture
below. The mass of the car is much smaller than the mass of the truck. At first the car doesn't
push hard enough on the truck to make the truck move. Then, as the driver of the car pushes
harder on the gas pedal, the car and truck begin to accelerate. Finally the car and truck are
moving along at the same constant speed.
F=ma
Place a check next to your predictions of the relative magnitudes of the forces between the car
and the truck. Be sure to have a good reason for each of your answers. Are you using the
Second or the Third Law to deduce your answer?
Before the car and truck start moving:
the force of the car on the truck > the force of the truck on the car
the force of the car on the truck = the force of the truck on the car
the force of the car on the truck < the force of the truck on the car
While the car and truck are accelerating:
---Y..-- the force of the car on the truck > the force of the truck on the car
the force of the car on the truck = the force of the truck on the car
the force of the car on the truck < the force of the truck on the car
While the car and truck are moving at a constant velocity:
the force of the car on the truck > the force of the truck on the car
the force of the car on the truck = the force of the truck on the car
the force of the car on the truck < the force of the truck on the car
Place a check next to your predictions of the relative magnitudes of the net forces on the car
and the truck. Be sure to have a good reason for each of your answers. Are you using the
Second or the Third Law to deduce your answer?
Before the car and truck start moving:
the net force on the car > the net force on the truck
the net force on the car = the net force on the truck
the net force on the car < the net force on the truck
While the car and truck are accelerating:
the net force on the car > the net force on the truck
the net force on the car = the net force on the truck
the net force on the car < the net force on the truck
While the car and truck are moving at a constant velocity:
the net force on the car > the net force on the truck
the net force on the car = the net force on the truck
the net force on the car < the net force on the truck
