## Net Force Quiz

 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 force of N is applied horizontally to a N box resting on a table. If friction acts with a force of N What is the acceleration (in m/s/s) of the box?

 2
A g container is sitting on a rough horizontal surface. When a N force is applied to the container horizontally it accelerates at m/s/s. What is the force of friction (in N) between the container and the rough surface?

 3
A rocket lifting off the Earth's surface weighed N and its motor developed an upward force of N. What was the rocket's acceleration?

 4
A N rocket lifting off the Earth's surface accelerated upward at m/s/s. What force did the rocket's motor supply (in N)?

 5
A rocket lifting off the Earth's surface develops an upward force of N accelerates at m/s/s. What is its mass (in kg)?
