A 129 kg crate is sitting at the top of a ramp, which is inclined at an angle of 20 degrees with respect to the horizontal. Someone gives the crate a quick shove to get
it moving, after which it slides down the ramp without any further assistance. The coefficient of kinetic friction between the crate and the ramp is ls = 0.23. What is
the magnitude of the acceleration (in m/s?) of the crate?
A 547g squirrel with a frontal surface area of 0.0145m2 falls to the ground from a 5.3m tree. Assume the density of air is 1.21kg/m3. What is the terminal velocity, in meters per second, of this squirrel? Use a drag coefficient of 0.70, and assume that down is the positive direction.
