The speed of a bobsled is increasing because it has an accelerationof 2.4 m/s2. At a given instant in time, the forcesresisting the motion, including kinetic friction and airresistance, total 450 N. The combined mass of the bobsled and it sriders 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?
