Aball is dropped into the oil. the position of the ball is given by the formula y(t) = a + bt +c e−dt, where y is given in m, and t is the time in s. at t = 0, y(0) = 0.06 m, the y component of the velocity is zero and the y component of the acceleration is ay(0)= 0.015 m/s2. as t approaches infinity, the y component of the velocity approaches vy([infinity]) = 0.4 m/s what is the formula for velocity?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
