Question
Transcribed Image Text:A box is sliding across a rough horizontal floor while Mary exerts a force on it. The magnitude of the kinetic friction component of the force the floor
exerts on the box is larger than the magnitude of the force that Mary exerts on the box. Which of the following must be true about the motion of the
box?
The box must be moving in the direction Mary is pushing.
The box must be moving opposite the direction Mary is pushing.
The box must be slowing down.
The box must be speeding up.

- The net force on a mass is zero. Which ONE of the following must be TRUE? The mass must be at rest. The speed of the mass is constant but the direction of motion may be changing. Both the speed and the direction of motion of the mass may be changing. The direction of motion of the mass is constant but the speed may be changing. O The velocity of the mass is constant.arrow_forwardPhysics student Matt has just learned about Newton's 3rd law of motion. He's considering a car pulling a trailer as shown below. T He thinks that since the tension force forward on the trailer is equal and opposite to the tension force backwards on the car, the net force on the car must be zero and therefore the car can't accelerate. Which one (or more) of the following statements is correct: The tension force forward on the trailer is not the same magnitude as the tension force backwards on the car. Matt has not considered all the forces acting on the car, such as the friction between the wheels and the ground, in order to calculate the net force on the car. The net force on the car is always zero and therefore the car cannot accelerate. Since the 2 tension forces act on different objects you can't add them together to get a “net force" on either object.arrow_forward200 N **26. Two strings are pulling on a 50-kg block as shown.
