Forces at work in stability are:
A.Hull strength and water resistance
B.Power & drag
C.Gravity & buoyancy
D.None of the above
Homework Answers
Correct answer is C.Gravity & buoyancy
Surfing is possible or floating is possible because buoyancy which is an upward force balances gravity which is a downward force

13) There are several types of drag on a car other than air resistance. Effects having to do with the squeezing of the tires (rolling resistance) and frictional forces in the drivetrain (the system that transfers energy from the engine to the rotation of the wheels) also must be taken into account. Engineers use the following equation to model the total force due to these different effects Fdrag=A+Bv+Cv2Fdrag=A+Bv+Cv2 For a Camry, these coefficients are estimated to be A=117.130A=117.130 N, B=1.800...
