1. The problem statement, all variables and given/known data A mass sits on the end of a spring and is at equilibrium. Code (Text): | | ,---. ___/'''\_ |/\/\/\/\/|_m_|________________()' o_____o '_________________ A car is costing gracefully towards the mass. The car has a semi-rigid rubber tire mounted on its front. The mass of the mass and mass of the car are approximately equal mass. When the car collides with the mass will the collision be elastic or inelastic? 2. Relevant equations There are basic equations for collision problems. In elastic collisions m1*v1_i + m2*v2_i = m1*v1_final + m2*v2_final In inelastic collisions m1*v1_i + m2*v2_i = (m1+m2)*v_f In both types of problems kinetic energy in conserved and m1*v1_i^2 + m2*v2_i^2 = m1*v1_final^2 + m2*v2_final^2 3. The attempt at a solution The problem is to determine what type of collision is at hand. As far as attempting a solution, I can't really go any farther than this.
