Answer on Mechanics | Relativity Question for Steve
square of her speed v, so that we can write air resistance as equal to kv2, where k is a constant independent of v. Thus, the faster she falls, the greater the air resistance.
(a) (12 marks) After the skydiver has been falling for some time, air resistance brings her acceleration to zero, so that she is now falling at constant speed u. Derive a
formula for u in terms of m, g and k.
(b) (8 marks) Derive the dimensions of the constant k in terms the fundamental dimensions of mass M, length L and time t
