and the mass of the bag is 0.45 ??. The board is at an incline of 15° above the horizontal. a. Draw a free-body diagram for the bag on the board. Mark the direction of motion and the direction of acceleration next to your free-body diagram. b. What is the magnitude of the normal
Dr. Knotts is playing in a Bags tournament. Every time he makes a toss, the bag slides off the back of the
board. He focuses very hard on his next toss to try to keep it on the board. His bag hits the board with an
initial velocity (parallel to the board) of 2.8
?
?
. The coefficient of kinetic friction between the bag and the
board is 0.12 and the mass of the bag is 0.45 ??. The board is at an incline of 15° above the horizontal.
a. Draw a free-body diagram for the bag on the board. Mark the direction of motion and the
direction of acceleration next to your free-body diagram.
b. What is the magnitude of the normal force on the bag?
c. What is the magnitude of the kinetic friction force on the bag?
d. What is the net acceleration of the bag? (magnitude and direction)

e. The bag lands on the board with 0.85 ? of board remaining. Does the bag stay on the board or
does it slide off of the back again? You will use a
