At the bottom of the arc, as in the figure, what is the direction of the net force on the falcon?
a-to the right, in the direction of the motion
b- up
c- the net force is zero
d- to the left, opposite the motion
e- down

Suppose the falcon weighs 5.0N and is turning with an acceleration of 14m/s^2 at the lowest point of the arc. What is the magnitude of the upward lift force at this instant?
a-5.0N
b- 10N
C- 12N
d- 7.1N

3. A falcon starts from rest, does a free-fall dive from a height of 30m , and then pulls out by flying in a circular arc of radius 50m . Which segment of the motion has a higher acceleration?
a- the two accelerations are equal
b- the circular arc
C- the free-fall dive

Explanation / Answer

1. (b) up 2. (c) 12 N 3. (b) the circular arc
