Homework Answers
An object is in complete equilibrium only if both net external force and net external torque are zero.
So, (2) Fnet=0 AND 
net=0 is correct.
Hence, first choice is correct.

6. A 32-pound object stretches a spring 8 feet to reach equilibrium. The object is then pulled to a point that is I foot below the equilibrium position and released from with an upward velocity of 6 feet per second Assume a damping force of 5. What is the position of the object when it attains its maximum displacement above the equilibrium position? Express your answer to 4 decimal places

Given information: An object is moving with velocity (in feet per second) described by the function v (t) = 4t + 1. We will reason about the object's position function, 8 (t). Question 1 How much does the position change over the time interval (0,4) Answer with a number only (units are feet) 36 Question 2 Question: Think back to the total change theorem. What additional Information would allow us to find a(4), the object's position at time t =...

For a particular spring, a 21lb object holds the spring in equilibrium at 3 feet. A 16 pound object is attached to this spring with friction (damping) constant 8 lb·s/ft. Assume the spring obeys Hook’s law. (a) Does this system have a non-zero force function? Pick one: ⃝ YES ⃝ NO (b) Write (and do NOT solve) the associated (spring/mass) equation of motion in an answer box.

An object stretches a spring 6 inches in equilibrium. Find its displacement y for t> 0 (where y is the displacement of the object from its equilibrium position, measured positive upward), if it's initially displaced 3 inches above equilibrium and given a downward velocity of 6 inches/s. Find the frequency, period, amplitude and phase angle of the motion.
