Textbook Question
Chapter 15, Problem 6AP
A 670-N swimmer oriented horizontally in freshwater has a body volume of 0.07 m3 and a center of volume located 3 cm
superior to the center of gravity.
a. How much torque does the swimmer’s weight generate?
b. How much torque does the buoyant force acting on the swimmer generate?
c. What can the swimmer do to counteract the torque and maintain a horizontal position?

A) Describe the difference between strength and power during a squat. Provide a quantitative example that illustrates the difference.
B) During a squat, the weight you have on your shoulders has a certain amount of gravitational potential energy. As you squat down and come to a stop at the bottom of the squat, some of that energy is lost. Where does it go?
A scientist was investigating if differences in the frictional work performed on a model car can change
depending on its mass (in grams) and whether the car moves up or down an inclined plane. They decided to
measure the amount of frictional force experienced by the model car and the distance it traveled in meters.
The scientists were able to evaluate the frictional work using the following data.
Mass (g)
Distance (m) Force
Work Done by Friction (J)
car going up the incline
100

0.063
2.457
car going down the incline 70

0.2309 ?
It is known that the relationship between force and distance determines the work done by friction (W+).
W₁ = fd
Wf work done by friction
f = force
d = distance
Question:
How much work done by friction was exerted on the car as it moved down the inclined plane?

Rotate the ball horizontally on an 80 cm long non-stretchable cord with angular
velocity of 3 s^(-1). After ten seconds of clockwise rotation, the cord breaks. At what
speed and in what direction does the ball fly, if it was faced north at time t = Os?
Where and after how much time does the ball land on the ground that is 1 m below
the plaine in which we rotate the string? {Solution: v= (0.37 m/s,2.37 m/s); d=1.07 m,
t=0.447 s.) }
