b. 48.44 N
c. 2471 N
d. 3460 N What does the coefficient of frictionrepresent?         a. the amount of friction present in a situation
b. the amount of force needed to change motion
c. the amount of inertia that must be overcome
d. the amount of stickiness two substances share

Explanation / Answer

Fn - mgcos = 0 Fn = mgcos ff = uFn ff = umgcos It's probably b if you take g = 10. Without more numerical information, it is difficult to evaluatethis question. Friction is b.
