A horizontal net force F is exerted on an object at rest. The object starts at x = 0m and has a speed of 4 m/s after moving 8.0 m along a horizontal frictionless surface. The net force F as a function of the object's position is shown below. what is the mass of thr object?

How would doubling the made of an object change the objects potential energy

An object has a weight of 500 on earth what is the mass of this object

How does the kinetic energy of a charge change as the charge moves under the effect of an electric field from higher potential to lower potential? a. the kinetic energy increases. b.the kinetic energy decreases. c.the kinetic energy remains the same. d.the kinetic energy is always zero.
