Problems for |
(a) Write Newton's second law as a vector differential equation for the vector velocity assuming that you can get away with assuming a purely viscous drag. (Not a good assumption!)
(b) Separate your vector equation into two ordinary differential equations for the x and y components of the velocity.
(c) Using your dimensionless form from last week, simplify and find a general solution for these equations.
(d) Show that the time that the ball is in the air satisfies the (dimensioned) equation
