Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a 100 kg ball traveling at 5 m/s.
A 1,000 kg ball traveling at 5 m/s would have
kinetic energy.
A 10 kg ball traveling at 5 m/s would have
kinetic energy.
A 100 kg person falling at 5 m/s would have
kinetic energy.
the pic i added is the answer choices for all three

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.
