5. (29pt) A crank-slider mechanism geometry & position are given in figure below. Calculate the angular velocity $\omega_{AB}$ and angular acceleration $\alpha_{AB}$ of link AB, for assumed velocity and acceleration of point C for this instant. (PS: For $V_C$ and $a_c$ use your last 2 number of your school ID respectively. If one of them is 0 then add 1 to it. For example: SchoolID is 250503105 than assume $V_C$ = 0+1 = 1 rad/s , $a_c$ = 5 rad/s$^2$).

(Experimental Probability HC) A coin is flipped at the start of every game to determine if Team A (heads) or Team B (tails) will get the ball first. Part A: Find the theoretical probability of a fair coin landing on heads. Part B: Flip a coin 12 times and record the frequency of each outcome. Determine the experimental probability of landing on heads. Please include the frequency of each outcome in your answer. Part C: Compare the experimental probability to the theoretical probability.

(2). Consider the case where a ternary complex, $E \cdot S_1 \cdot S_2$, forms with two different substrates, $S_1$ and $S_2$, attached to the enzyme, $E$, which has pone active site. A possible reaction mechanism for this situation is shown below. Equilibrium Dissociation Constants $E + S_1 \rightleftharpoons E \cdot S_1$ $K_1$ $E + S_2 \rightleftharpoons E \cdot S_2$ $K_2$ $E \cdot S_1 + S_2 \rightleftharpoons E \cdot S_1 \cdot S_2$ $K_{12}$ $E \cdot S_2 + S_1 \rightleftharpoons E \cdot S_1 \cdot S_2$ $K_{21}$ $E \cdot S_1 \cdot S_2 \xrightarrow{k_2} E + P$ (slow) Assuming that the first 4 reaction steps are at equilibrium, derive the rate of product formation for the above reaction scheme. Show that $K_1 \cdot K_{12} = K_2 \cdot K_{21}$. What does your rate law expression reduce to when $S_2$ is in great excess?
