As the angle of the incline increases, what happens to the normal force?
The normal force increases
The normal force decreases
The normal force is not affected by the incline
The normal force is only dependent on the force due to gravity
Given the FBD, which of the following must be true?
The frictional force must be accelerating the system to the left.
The box must be accelerating to the right.
The box must be moving to the right.
The FBD is incorrectly drawn. This situation isn't possible
Which of the following statements is true about the image above?
The accelerations of the blocks will vary according to their mass
The net force acting on each block is the same
The blocks will experience the same acceleration
The 3m box will eat the 2m and the m boxes
Sam is hover boarding down they hall at a constant velocity. Assuming there is friction, which of the following must be true?
The force applied by the board must be greater than the frictional force
The frictional force must equal the force applied by the board
The force applied must equal zero
There is not enough information
If there is no friction, then the acceleration would be equal to
mg
sin(θ)mg
g
sin(θ)g
If μk = 0.65 and μs = 0.7, acceleration would be equal to
0 m/s/s
9.8 m/s/s
3.35 m/s/s
-2.63 m/s/s
Three forces of equal magnitude act on the box shown. One force is upward, one downward, and one rightward. Which of the following statements must be true based on this information? Select two answers.
The box must have a rightward component of velocity.
The box has no vertical component of velocity.
The acceleration of the box is directed to the right.
The velocity of the box is changing with time.
