Chapter 4, Problem 4.196(choose chapter or problem)
The speed of a bobsled is increasing because it has an acceleration of 2.4 m/s2 . At a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 450 N. The combined mass of the bobsled and its riders is 270 kg. (a) What is the magnitude of the force propelling the bobsled forward? (b) What is the magnitude of the net force that acts on the bobsled?
