Find the momentum for a 2.6-kg brick parachuting straight downward at a constant speed of 8.4 m/s .

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.

Which of the following is an example of units for speed
