5) Projectiles with some initial rotational momentum have greater gyroscopic and aerodynamic stability. A process called 'rifling' involves placement of spiral grooves in the inside of a gun barrel in order to generate some rotation for the outgoing projectile. Examine the rubber bullet design shown a) Calculate the total volume of the rubber bullet. b) Calculate the total mass of the bullet, if the density of the rubber that is used is 3.0 g/cm. (Note the units). c) We are interested in studying the rotational behavior of the rubber bullet. Calculate the mass moment of inertia of the bullet, about its centroidal axis. d) What is the radius of gyration for this bullet (about its centroidal axis)?
