Question: a= b= Consider the function f(z) = 5z + az + bz 2 where z = C, and a, b R. If z =

a= b= Consider the function f(z) = 5z + az + bz 2 where z = C, and a, b R. If z = + is a solution to f(z) = 0, determine the values of a and b. QUESTION 2 Motorbike A has mass 407 kg and is travelling at 13 m/s heading South. Motorbike B has mass 361 kg and is travelling in the direction S83W at 21 m/s. If the two motorbikes collide and move off together, determine their speed in metres per second after the collision giving your answer to one decimal place.
