Question 1 (25 marks) a) Consider the following differential equation dv +B M o dt dt where v is a velocity and M a mass. The parameters of the system are: e M:the mass (kg) e u:a constant velocity of ejected mass (m-s~1) e h:the height of the object (m). Using dimensional analysis find the parameters composing B. B should be of the form B=k M*-uP-h* where k is a dimensionless constant. (8]
