A5 kg book rests on a table. how much force is it exerting on the table?
(hint: think about acceleration due to gravity.)

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Aforce of 100 newtons is used to move an object a distance of 15 meters with a power of 50 watts. find the work dine and the time it takes to do the work
