Question

3. A powerful motorcycle can produce an acceleration of while traveling at 90.0 km/h. At that speed the 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 force does the motorcycle exert backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245 kg

Answer 1

Total force = 1257.5N

Step-by-step explanation:

Acceleration = 3.50 m/s2

Total Mass = 245kg

Force = Mass x acceleration

Force = 245 x 3.50 = 857.5N

Opposing Force = 400N

Total Force = Force of Motorcycle + Opposing force

Total force = 857.5N + 400N

Total force = 1257.5N
