A physics major is cooking breakfast when he notices that the frictional force between the steel spatula and the Oiled Steel frying pan is only 0.100 N. Knowing the coefficient of kinetic friction between the two materials (0.03), he quickly calculates the normal force. What is it

Fk = μk η

0.100=0.03η

η= 0.100/0.03

η= 3.333N

Explanation:

Fk = μk η

Fk = force of kinetic friction

μk = coefficient of kinetic friction

η = normal force (Greek letter "eta")

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
