Just multiply the weight by each coefficient, add them together and multiply by 9.8

How do you find the coefficient of static friction?
Use the formula: FsMAX=μsFN if you want to do it experimentally, get the two different surfaces, and angle one until the object on top starts moving. take the tangent of the angle that starts the objects sliding past one another, and that is your coefficient of static friction.
Hail falls to the ground because of the force of?
When hail falls to the ground, it is because of the force of FRICTION!! :)
What might parachutists do to speed up their rate of fall?
They would have to reduce friction by becoming perpendicular to the ground and reduce their surface area.
Why ligthining in thunder storm?
Friction in the cloud creates static charge. Eventually the charge becomes big enough and 'jumps' to the ground.
Are tornadoes and avalanches similar?
No. An avalanche is a large mass of snow and ice sliding down the side of a mountain. A tornado is a violently rotating column of air extending from a thunderstorm to the ground.
When does sliding friction occur?
Sliding Friction Occurs When And Object Is Being Slided On The Ground
What is sliding fricion?
If you mean sliding friction, it's the friction generated by two objects sliding past one another. (Like when you rub your hands together when they get cold--the friction generates heat.) Sliding friction is also the main force which slows down a ball rolling on the ground; the two objects sliding past each other are the ground and the ball, and that creates friction.
Why is a tire rolling on the ground rolling friction?
Friction is the resistance to sliding and as a tire rolls it does resist friction, otherwise it would slide.
How does friction apply to running?
It slows your speed down every time your feet touch the ground.
Example of where you need friction?
The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.
What is the minimum rate of flow at which a stream of water can maintain the transportation of 1.0 centimeters in diameter?
You would have to know the weight or density of the pebbles, the coefficient of friction on the pebble's surface and the coefficient of friction on the ground.
What is the difference between sliding and rolling and kinetic and static friction?
Sliding friction is the friction between the body and the surface on which the body is sliding. Static friction however, is the friction when the body isn't moving when you aply force to it. The force of static friction is the same as the force you are pushing the body UNTIL it moves!..It's a fact that the static friction coefficient is a bit bigger than the sliding friction coefficient.
What force keeps our feet sliding when walking or running?
frictional force which is generated due to interlocking of minute roughness of slipper / shoes/foot with those of floor
A sled of mass 53.0 kg is pulled along flat snow-covered ground The static friction coefficient is 0.30 and the kinetic friction coefficient is 0.10 a What force will be needed to start the sled movin?
Ignore the kinetic friction coefficient, that is only in the problem to trick you. If the force pulling the sled is parallel to the ground, then the problem should be pretty easy. Acceleration due to gravity = 9.8 m/s^2
Why is sliding friction less than static friction?
Because when an object is sliding on the other the molecules donnot get time to inter lock properly
What is the maximum acceleration a car can undergo if the coefficient of static friction between the tires and the ground is 0.78?
coefficient of friction = 0.8 tan theta use your calculator : 2nd tan ( 0.8) = 38.66 degrees
Why increase friction?
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
