1.) An athlete slides down from rest 40.0 meter along an icy hill which is 35 degrees from the horizontal. He then continues sliding on the level ice.
a) If the coefficient of kinetic friction between the athlete and ice is 0.20 (neglect air resistance) find speed (m/s) of athlete at the foot of the plane.
b) ) find the distance (m) from the foot of the plane to the point where he has landed to the level ice

Example
A raindrop with radius R= 1.5 mm falls from a cloud that is at height h
the ground. The drag coefficient C for the drop is 0.60. Assume that the drop is spherical
throughout its fall. The density of water) Pw is 1000 kg/m³, and the density of air pa 1S
1.2 kg/m³) If you know that the raindrop reaches terminal speed after falling just a few
meters. What is the terminal speed?

- You have been called as an expert witness for a trial in which a driver has been charged with speeding but is claiming innocence. He claims to have slammed on his brakes to avoid rear-ending another car, but tapped the back of the other car just as he came to rest. You have been hired by the prosecution to prove that the driver was indeed speeding. You have received data as follows from the police: Skid marks left by the driver are 56.0 m long and the roadway is level. Tires matching those on the car of the driver have been dragged over the same roadway to determine that the coefficient of kinetic friction between the tires and the roadway is 0.82 at all points along the skid mark. The speed limit on the road is 35 mi/h. Construct an argument to be used in court to show that the driver was indeed speeding.arrow_forwardDescribe a situation in which the net external force on a system is not zero, yet its speed remains constant.arrow_forward5.) -1.7 m A D 1.8 m 2.5m 12 m B 0.75 m Crate D has a mass of 250 kg and Crate C has a mass of 300 kg are in the back of the pickup truck.
