Rocket in interstellar cloud

Rocket in interstellar cloud

cylindrical rocket of diameter 2R and mass M is coasting through empty space with speed v0 when it encounters an interstellar cloud. The number density of particles in the cloud is N particles/m3. Each particle has mass m M, and they are initially at rest.

(a) Assume that each cloud particle bounces off the rocket elastically, and that the collisions are so frequent they can be treated as continuous. Prove that the retarding force has the form bv2, and determine

b. Assume that the front cone of the rocket subtends angle a = p/2, as shown.

(b) Find
