The masses of the objects are m1 = 18.0 kg and m2 = 11.5 kg, the mass of the pulley is m = 5.00 kg, and the radius of the pulley is r = 0.300 m. object m2 is initially on the floor, and object m1 is initially 4.40 m above the floor when it is released from rest. the pulley's axis has negligible friction. the mass of the string is small enough to be ignored, and the string does not slip on the pulley, nor does it stretch. a. how much time (in s) does it take block m1 to hit the floor after being released?
b. how would your answer to part (a) change if the mass of the pulley were neglected? (enter the time, in seconds, it takes block m1 to hit the floor if the mass of the pulley were neglected.)

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

electrical power

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.
