Answer:

a. 2000 N

b. acceleration of the motorcycle would decrease

Explanation:

a. acceleration = (final speed - initial speed)/time

a = (30 - 0)/3 = 10 m/(s^2)

Force = mass * acceleration

F = 200 * 10 = 2000 N

b. If the the coefficient of friction between the tire and the pavement increased greatly, part of the force generated by the engine would go to overcome this friction, then the force that goes into acceleration of the motorcycle would be less than case a, as a consequence, its acceleration would decrease (mass remains the same).
