The speed of a bobsled is increasing because it has an accelerationof 2.1 m/s2. At a given instantin time, the forces resisting the motion, including kineticfriction and air resistance, total 450 N. The mass of the bobsledand its riders is 240 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?
