Which of the following is not true about the system?
T3 is equal to the scalar sum of the magnitudes of T2 and T1
T3 is equal in magnitude to Fg

The system is in equilibrium.
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
What are the TWO equilibrium cases for forces acting on an object?
When the object is moving at a constant velocity
The object is speeding up
The object is at rest
The object is slowing down
Imagine that this device was set on a cart. If the cart starts moving, which bucket will move farther back and why?
The empty bucket because it has more inertia.
The empty bucket because it has less inertia.
The full bucket because it has less inertia.
The full bucket because it has more inertia.
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.
A cart is constrained to move along a straight line. A varying net force along the direction of motion is exerted on the cart. The cart’s velocity v as a function of time t is shown in the graph above. The five labeled points divide the graph into four sections. Which of the following correctly ranks the magnitude of the average acceleration of the cart during the four sections of the graph?
aCD > aAB > aBC > aDE
aBC > aAB > aCD > aDE
aAB > aBC > aDE > aCD
aCD > aAB > aDE > aBC
