A 2 N and an 8 N force pull on an object to the right and a 4 N force pulls on the same object to the left. If the object has a mass of 0.5 kg, what would be its acceleration? You must draw a picture to support your answer.

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.
