Problem 1 A car is negotiating a horizontal circular turn at a speed of 21 mfs when the road is wet and the maximum static frictional force acts on the tires. Up ahead, there is a deep puddle patch in the road which causes the maximum static frictional force to decrease to one-half of its initial value. If the car is to continue around the curve without slipping, to what speed must the driver slow the car? Problem 2 A 560-g squirrel with a surface area of 144 cm2 falls from a 5.0 m tree to the ground. (a) Estimate its terminal speed assuming it has the drag coefficient of a horizontal skydiver. (b) What would be the impact speed of a 56-kg person hitting the ground, assuming no air drag during this same fall distance? (c) In a sentence or two, give solid reasoning why the squirrel will not reach terminal speed before hitting the ground
