A powerful motorcycle can produce an acceleration of 3.50m/s^2 while traveling at 90.0 km/h. At that speed forces resisting motion, including friction and air resistance, total 400 N. (air resistance is analogous to air friction. It always opposes the motion of an object.) What is the magnitude of the force the motorcycle exerts backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245kg?
