I want to see the solving steps

4.214 N

Explanation:

Since the ball reaches a constant terminal velocity, then the net force = 0 because the acceleration = 0

If we draw a free body diagram, we will find that all forces acting on the ball are:

If F(net) = 0, then gravitational force = air resistance = Mass * free-fall acceleration = 0.43*9.8 = 4.214 N

d. air pressure decreases as altitude increases.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
