The motion of an object falling from rest under gravity, subject to a drag force proportional to the square of the speed, may be modelled by the initial value problem (IVP): -=g-ev², v(0)=0. Here v is the speed of the object, t is time, g is gravitational acceleration (assumed constant) and is a constant. (a) Without solving the IVP, briefly describe how you expect v to vary with t. (b) (c) (d) (e) dv dt Show that under the changes of variable x = (Eq. 4.1) becomes: dx dr ==1-x², x(0)=0. 1 A B 1-x² 1-x 1+x 1/2 (9) v, t = (eg)¹²t, the IVP given by g X = (Eq. 4.1) The IVP given by (Eq. 4.2) is of separable type. Briefly explain what this means (you do not need to solve the IVP at this stage). arks] Find A and B such that: Using your answer to (d), solve the IVP (Eq. 4.2) and show that: 1-e-2r 1+e=2r (Eq. 4.2) AS
