A basket of negligible weight hangs from a vertical spring scale of force constant 1500 N/m . If you suddenly put an adobe brick of mass 3.00 kg in the basket, find the maximum distance that the spring will stretch. Check all that apply.

a. The spring is initially unstretched.
b. After the brick has been placed in the basket, the spring is stretched.
c. When the brick is first placed into the basket, it has zero velocity.
d. When the spring is stretched to the maximum amount, the brick has zero velocity.
e. The brick’s final position is lower than its initial position.

what question you dont ask a question

explanation:

current flows in a wire

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
