Transcribed Image Text:To complete a scene of firefighters in a television program, they need the 98 kg actor to slide down a
vertical tube at a certain height h from the ground, the actor starts from rest and reaches the ground
with a speed of 3.5 m/s. If the tube produces a constant friction of 794 N during descent, from what
height h did the actor's motion begin?
a) 7.2145 m.
b) 0.625 m.
c) 0.0078 m.
d) 3.6073 m.

There’s some air resistance occurring, and the man’s upward trajectory ends 6.0 meters below the ledge. A) What was the average force of frictional air resistance the man experienced during his upward motion?
