1.Hold a single coffee filter in your hand. Release it and watch it fall to the ground. Next, nest two filters and release them. Did two filters fall faster, slower, or at the same rate as one filter? What kind of mathematical relationship do you predict will exist between the velocity of fall and the number of filters? 2.If there was no air resistance, how would the rate of fall of a coffee filter compare to the rate of fall...

Th figure below shows a mass m=1.0 kg which is initially moving
with speed v=7.2 m/s at the top of a frictionless hill of height
h=4.9 m. It slides down the hill until it encounters a flat section
with unknown coefficient of kinetic friction µk. If the object
travels a distance D=11.1 m before reaching a speed of v/2, what is
the coefficient of kinetic friction µk? (use picture, but first
question)

A car travels around flat, un-banked, circular track with a maximum speed of 20 m/s. If the coefficient of friction between the car tires and the track is 1.0, and the normal force between the car and the track is due to the weight of the car (no aerodynamic effects), what is the radius of the track?
