Two forces are applied to a car in an effort to move it, as shown in the figure below. (Let F1 = 425 N and F2 = 365 N. Assume up and to the right are in the positive directions.) (a) What is the resultant vector of these two forces? (b) If the car has a mass of 3,000 kg, what acceleration does it have? Ignore friction.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
