Problem 19.

given: g=9.81 m/s^2.

A 52.2 kg driver steps off a diving board and drops straight down into the water. The water provides an average net force of resistance of 1518 N to the diver's fall.

If the diver comes to rest 5.2 m below the water's surface, what is the total distance between the diving board and the diver's stopping point underwater? Answer in units of m.

Problem 11.

Given: g =9.81 m/s^2

A 2.6*10^3 kg car accelerates from rest at the top of a driveway that is sloped at an angle of 19.1 degrees with the horizontal. An average frictional force of 4.2*10^3 N impedes the car's motion so that the car's speed at the bottom of the driveway is 4.1 m/s.

What is the length of the driveway? Answer in units of m.
