A 3000-kg wagon accelerates at 2.5 m/s2. What is the net force acting on the wagon?

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.

The midpoints? a, b, and c are marked on the histogram. match them to the indicated scores. which? scores, if? any, would be considered? unusual?

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?
