B22 A body moving through air at a high speed e experiences a retarding force F given by F = kApe" where Ais the surface area of the body, p is the density of the air and kis a numerical constant. Deduce the value of x. A sphere of radius 50 mm and mass 1.0kg falling vertically through air of density 1.2 kg m attains a steady velocity of 11.0ms. If the above equation then applies te its fall what is the value of k in this instance?
