Do all objects in free fall reach terminal velocity because I
thought objects in free fall always accelerate with 9.8 m/s/s so
why is there a point where they stop accelerating
Calculate the terminal velocity in free fall of a bowling ball
(mass of 7.2 kg, diameter of 21.6 cm) and a basketball (mass of
0.51 kg, diameter of 23.85 cm). The bowling ball can be considered
a smooth sphere (Cd = 0.1), while the basketball
can be considered a rough sphere (Cd = 0.4). What
would be the terminal velocity of the basketball if we considered
it a smooth sphere?
On the way up, the magnitude of the ball's acceleration is _____.A ball is tossed straight up. Air resistance is not negligible; the force of air resistance is opposite in direction to the ball's velocity. Assume its magnitude is less than the ball's weight. Answer choices:(a) Less than g(b) Equal to g(c) Greater than g
Acceleration of an object in free fall motion is 9.81 m/s^(2).
Sometimes the question asks a question, some answers write the
acceleration as negative and sometimes as a positive!. Can somebody
tells me when should I write it as a negative and when it’s
positive?.

Theory: for several centuries, it was believed that heavy objects
fall to the earth at a faster rate than lighter ones. Galileo
(1564-1642) performed experiments to show that this was not true.
He showed that it was possible for light objects to fall at the
same rate as their heavy counterparts. Please watch the following

Draw a 1). position graph, 2). velocity graph, and 3). acceleration
graph of a person standing one second, then goes down into a squat
for three seconds, back up for one second and then a one second
stand for the first rep.
2nd rep- this person goes back down for three seconds, and
then has a one second pause at the bottom of the squat, and then
back up for one second.
A particle moves with acceleration function a(t) = 2x+3. Its
initial velocity is v(0) = 2 m/s and its initial displacement is
s(0) = 5 m. Find its position after t seconds.
