 1
A crate slides down a ramp with an acceleration of m/s/s when the ramp makes an angle of º to the horizontal. At what angle would the crate slide with constant velocity?

 2

Two carts on a frictionless surface are being pulled by a N force 30º above the horizontal as shown. Cart A is kg, and cart B is kg. What is the tension (in N) in the string connecting the carts?

 3
A block has a coefficient of friction of with a plane that is inclined º above the horizontal. What is its acceleration (in m/s/s) along the plane?

 4

What is the acceleration of block A (in m/s/s), neglecting friction? Block A is kg, and block B is kg.

 5
If the acceleration of block A in question 4 is m/s/s what is the coefficient of friction?
