I need to answer some physics word problems related to the work-energy theorem; this is the first one: "An 1100 kg car accelerates from rest to 12 m/s over 150 m. (a) How much work was done to the car (remember: work = change in kinetic energy)? (b) What was the magnitude of the net force acting on it?" I'm also given the answers, but I need to show the work leading up to it. The answers are 79,200 Joules for A and 528 Newtons for B.

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.

Find the dimensions and area of the largest rectangle that can be inscribed in the upper half of the ellipse. (give your answers in terms of a and b. enter the dimensions as a comma-separated list.)
