A physic student sets out to experiment on the effect of drag forces on a ball of mass m by giving the ball an initial velocity nu_0 upwards and then downwards as describe below. In both cases, the ball experiences a force of air resistance whose magnitude is given by F = -k nu Where k is a positive constant. The positive direction for all vector quantities is taken to be upwards. Express all algebraic answers in terms of m....

The aerodynamic forces produced by a golf ball (lift and/or drag) depend on its diameter d, its speed V, its angular velocity w, and its dimple height h, as well as the air density p and viscosity . (a) You wish to define a force coefficient (a dimensionless force). Find an variables by which you can divide the force to make a dimensionless force coefficient. Show your work. appropriate combination of the above (b) Show that the appropriate dimensionless force...
