Asap plz. true or false: when placing a fulcrum in a lever, to get the greatest mechanical advantage, you would need to make the length of the effort arm greater than the length of the load arm. why?

be sure of your answer

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

There are two routes similar in terrain; however, one route has an incline of approximately 28 degrees, and you must decide on which route to take. what is the maximum road grade that your fully loaded ecv can climb?

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
