Question

A kid is on a stationary sled,on snowy ground with Us=0.125. It takes 71.2N of force to get the sled moving. How much normal force is acting?

Answer 1

Correct Answer:

570 N

Answer 2

570 N

Step-by-step explanation:

Friction = normal force × coefficient of friction

F = Nμ

71.2 = N (0.125)

N = 569.6

Rounded to 3 significant figures, the normal force is 570. N.
