1-A bullet moving horizontally with a speed of 600 m/s strikes asandbag and continues for a distance of 20 cm.
A-What is the average acceleration of the bullet?
B-How long does it take to come to rest?
2-A 45.0 kg skier, starting from rest, begins skiing straightdown an incline on the mountain of 12.5. The coefficient of kineticfriction between skis and snow is 0.08.
A-Draw a free body diagram of the skier and the forces acting onthe skier.
B-Calculate the Normal force acting on the skier
C-Calculate the force of kinetic friction acting on theskier
D-Calculate the acceleration of the skier
E-The skier travels a distance of 150 m down the mountain. Whatis her final speed after 150?
