The speed of a bobsled is increasing because it has anacceleration of 2.6 m/s2. At agiven instant in time, the forces resisting the motion, includingkinetic friction and air resistance, total 450 N. The mass of the bobsled and its riders is 255 kg.
a) What is the magnitude of the for cepropelling the boblsed forward?
b) What is the magnitude of the net force that acts on the bobsled?
