Wells Problem Workbook Pack
... Just look at the y axis and read off the axis what the velocity is, include a direction with the answer. - Displacement at a certain time (implies from when you started until that time), Find the areas between the motion line and the x axis for each section from start to the point in question. If yo ...

Chapter 7 - Work & Energy
... Example 7-1: Work done on a crate. A person pulls a 50-kg crate 40 m along a horizontal floor by a constant force FP = 100 N, which acts at a 37° angle as shown. The floor is smooth and exerts no friction force. What is (a) work done by each force acting on the crate, & (b) net work done on the cra ...

... BIG IDEA 3: The interactions of an object with other objects can be described by forces. 3.D.1.1: The student is able to justify the selection of data needed to determine the relationship between the direction of the force acting on an object and the change in momentum caused by that force. [SP 4.1] ...
