A 10 lb block with an applied force P = 2 lb is in equilibrium. What is the magnitude of the friction force between the block and the surface? The coefficient of static friction is 0.3 between the block and the surface.

Explanation:

Weight of block = mg

= 10 x 32 = 320 poundal.

frictional force ( maximum )

= coefficient of friction x weight of block

= .3 x 320

= 96 poundal.

Applied force = 2 x 32 poundal

= 64 poundal .

Since applied force is less than max frictionl force possible , so

the block must not be moving .

magnitude of frictional force = applied force

= 64 poundal.

it is b

explanation:

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong
