Do the Work

DoNow: A 50 N force directed 36.9 degrees above the horizontal is used to accelerate a mass 10 m along a frictionless, horizontal surface. Calculate the horizontal and vertical component of force. Calculate the horizontal and vertical work. Describe the total work done by the 50 N force. Calculate the speed of the 2 kg object after traveling 10 m. (notes)

AIM: I can describe the equations used for energy and the relationships described by the Work-Energy Theorem and the Conservation of Energy.
