if come convinced yuor friend to lend you her notes to study for an exam, what would this situation be an example of?

In one eight-hour workday, a forklift operator at a particular distribution warehouse lifts a total of 100,000 N of boxes. Each box must be lifted to a height of 1.5 m and carried an average of 10 m to the shipping dock.

A truck covers 40.0 m in 8.50 s while smoothly slowing down to a final speed of 2.80 m/s. (a) find its original speed. (b) find its acceleration.

On a cloudless day, the sunlight that reaches the surface of the earth has an intensity of about 1.40 * 10 3 1.40*103 W/m². What is the electromagnetic energy contained in 6.00 m³ of space just above the earth's surface?
