Adisk with a uniform positive surface charge density lies in the x-y plane, centered on the origin. the disk contains 2.5 x 10-6 c/m2 of charge, and is 7.5 cm in radius. what is the electric field at z?

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.
