A force of 30 N accelerates a 2.0 kg object from rest for a distance of 3.0 m along a level, frictionless surface; the force then changes to 15 N and acts for an additional 2.0 m. (a) What is the final kinetic energy of the object? (b) How fast is it moving?
17. A net force of 24 N is acting on a 4.0-kg object. Find the acceleration in m/s2
Three forces acting on an object are given by # = (-2.21 + 7.155) N, F2 = (4.559 – 2.55) N, and F3 = (-49.51) n.
