Transcribed Image Text:
1) For the diagram below, you are looking down from above at a puck sliding on a frictionless
tabletop. The puck is sliding at a constant speed along a circular fence and just leaves
contact with the fence at position B. The fence and puck are also frictionless.
B
a) On the top drawing draw vectors and label them for any forces
acting parallel to the table top on the puck at positions A and
B.
b) On the side views below, draw vectors and label them for any
forces acting perpendicular to the tabletop.
side view at A
side view at B
B
c) Which of the forces above are inward forces?
d) Which of the forces above are outward forces?
e) What would be the equation for the net force on the puck?
f) On the top drawing at position B draw a line at least an inch
long showing the path the puck will travel after point B. How
do you know?
g) On the bottom drawing, draw and label a velocity and an
acceleration vector on the puck at positions A and B.
h) At position A is the net force on the puck zero? How do you
know?
i) At position B is the net force on the puck zero? How do you
know?
