mass m initially at speed u collides head-on (without rotation) with a stationary puck of mass M. Find the velocities of both puck after the collision if: i) the collision is fully elastic ii) the collision if fully inelastic. i) momentum: kinetic energy: mu = mv+MV (+ve in direction of initial u) 1 /2 m u2 = 1/2 m v2 + 1/2 M V2 2 eqns in 2 unknowns: V = (u - v) m/M substitute in K eqn: u2 = v2 + (M/m) V2 = v2 + (M/m) (u - v)2 (m/M)2 = v2 + (u - v)2 (m/M) let ρ = (m/M) ⇒ v2 (1 + ρ) - 2ρ u v + u2

BIO 205 Professor: Jill Raymond Aerobic Energy Production Glycolysis Also known as sugar splitting. Takes place in the cytoplasm. There are 8 steps in glycolysis and each steps need a specific enzyme to catalyze. At the end of glycolysis‚ glucose (6 C) is broken into 2 pyruvic acid (3 C) 2 ATP is produced and 2 NADH come in to keep the energy released from broken bonds. The Bridge Before going to the Kreb’s cycle 2 pyruvic acid (3C) becomes 2 Acetyl CoA (2 C). As a result‚ 2CO2 is produced
