New Problems reloads the page with new variable values in all questions. You must do this after grading the test to rework it another time.
Make sure to enter your answers in the specified units .
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?
