Dynamics Physics

The following formula is used to calculate the: (a)   of a vector. $$\sqrt[]{\left(X_{comp}\right)^2+\left(Y_{comp}\right)^2}$$  

A force of 8 Newton’s is applied to a crate so that it moves at a constant velocity of 1.5 m/s. What is the magnitude of the frictional force?

What happens to the acceleration of an Atwood machine as the difference between the two masses increases?

Which of these is a correct sum statement for Fx?

What's happening in this FBD?

Here are 3 FBD diagrams for an elevator. Consider them to be A, B, C. Which one shows an elevator accelerating upward?

Here are 3 FBD diagrams for an elevator. Consider them to be A, B, C. Which one shows an elevator moving upward but braking?

The box on the incline is at rest due to friction. Which of these calculations would allow you to get the frictional force?

If you were trying to quickly determine the static coefficient of friction, you'd raise the plank until the block just starts to slide and do what?

Calculate the normal force for this situation if the angle is 30 degrees and the mass of the box is 1.5 kg.
