A free-body diagram of a ball in free fall in the presence of air resistance would show a downward arrow to represent the force of air resistance.
only a downward arrow to represent the force of gravity.
a downward arrow to represent the force of gravity and an upward arrow to represent the force of air resistance.
an upward arrow to represent the force of gravity and a downward arrow to represent the force of air resistance.

a downward arrow to represent the force due to gravity and an upward arrow to represent the force of air resistance.

Explanation:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
