A physics major is cooking breakfast when he notices that the frictional force between the steel spatula and the Teflon frying pan is only 0.200 N. Knowing the coefficient of kinetic friction between the two materials (0.04), he quickly calculates the normal force. What is it (in N)?
we know that the frictional force is equal to N (coefficient
of kinetics friction* Normal)
Here *N= friction
So, N=0.2/0.04= 5 Newton
The normal force is 5N in magnitude.

1) Let's practice calculating the frictional force of a skier on old "woody" skis and wet snow. The skier has a mass of 58 kg. The coefficient of kinetic friction of wood skis on wet snow is 0.1 Notice there are no units for the coefficient of friction. What is the kinetic frictional force between the wood skis and the snow? Answer: ?? 2) Do you remember Newton's 2d Law? F = ma? What is the magnitude (meaning we are...
a) When rebuilding her car's engine, a physics major must exert 445 N of force to insert a dry steel piston into a steel cylinder. What is the magnitude if the normal force in newtons between the piston and cyliner? b) What is the magnitude of the force in newtons she would have to exert if the steel parts were oiled?
what can be said about the relationship between the frictional
force as the angle of the of the system is releaed from 89 degrees
and decreses to zero. the same for the normal force. what is the
telationship between the frictional force and normal force in this
sitiation.
refer to the last photo for context on the graphs.

a) If half of the weight of a flatbed truck is supported by its two
drive wheels, what is the maximum acceleration (in m/s^2) it can
achieve on dry concrete where the coefficient of kinetic friction
is 0.7 and the coefficient of static friction is 1.
The answer is 4.9 m/s^2.
b) Will a metal cabinet lying on the wooden bed if the truck
slip if it accelerates...
(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
