... An inertial reference frame is one in which Newton’s first law is valid.This excludes rotating and accelerating frames. An example is a cup resting on the dashboard of a car. It will stay at rest as long as the car’s velocity remained constant. If the car is accelerating, the cup may begin to move t ...

... 41. An object of mass 20.0 kg and initial velocity 10.0 m/s, 0.0º is subject to a certain force that acts for a certain period of time. The final velocity of the object is 5.00 m/s, 90.0º. What is the magnitude of the net impulse that acts on the object, causing this change? 42. Fuel is burned at a ...
