2. Below are four velocity vs. time graphs. Which graph represents the motion of an object that has a constant positive acceleration? Explain why you chose that graph.
See picture, thanks!

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

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.
