An applied force of 20N is used to accelerate a specific object to the right across a surface with friction. The object encounters 10N of friction. Use the diagram below to determine: the normal force, the net force, the coefficient of friction (μ) between the object and the surface, the mass, and the acceleration of the object. (Neglect air resistance.) What is Fn? (same as Fg)
a. 100 N
b. 10.2 N
c. 10 N
d. .98 N
What is Fnet? (add/subtract vectors)
a. 100 N right
b. 10.2 N left
c. 10 N right
d. .98 N left
What is the coefficient of friction? (mu=Ff/Fn)
a. .1
b. .01
c. 10
d. .001
What is the acceleration of the object? (a=Fnet/m)
a. 10.2 m/s/s left
b. 100 m/s/s left
c. .98 m/s/s right
d. 98 m/s/s right
What is the mass of the object? (m= Fg/g)
a. 5 kg
b. 100 kg
c. 10.2 kg
d. 1 kg
