Consider a weight held in place by spring. at rest, the height of the weight is . the mass of the weight is . the spring constant is . the frictional losses are characterized by the constant . the force applied to the weight after is . this leads to the ode 1. (15 points) if and , what mass will result in a critically damped system? 2. (15 points) if , , and and 1 n of force is applied continuously to the mass what is the maximum distance the mass will move from its initial position? 3. (20 points) if 1 n of force is instantaneously transferred to the system described in problem 3 at , what is the response? that is, what is ?

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

think its the third option

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.
