Part d next use the charts tab enter the settings noted and answer the question
click the reset all button to restore all the settings to zero set a small constant a on the acceleration slider and check the show vector box below it click play watch and describe what’s happening with the displacement velocity and acceleration graphs

i need help i want to put it in my own words

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.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
