Question 1

A heavy weight is supported by two cables that exert tensions of magnitude T1 and T2. Which statement is correct?



◦
T1 = T2.

◦
T1y = T2y.

◦
T1>T2.

◦
T1<T2.

◦
We need the mass of the box in order to determine the correct answer.


Question 2

A juggler throws two balls up to the same height so that they pass each other halfway up when A is rising and B is descending. Ignore air resistance and buoyant forces. Which statement is true of the two balls at that point?

◦
There is an residual upward force from the hand on each ball.

◦
There is a greater residual force from the hand on A than there is on B.

◦
Only gravity acts on B but there is an additional residual force from the hand on A.

◦
There is an additional downwards force besides gravity on each ball.

◦
The only force acting on each ball is the gravitational force.
