Problem 2 (25 pts) Two smooth balls, each of mass m, have the velocities shown just before they collide. If the velocity of A after impact is in the direction shown, determine (a) the post-impact speed of A, $v_A^+$, as a function of $v_0$ (b) the post-impact velocity of B, $\vec{v_B}^+$, as a function of $v_0$ and using the given component system (c) the coefficient of restitution e for the impact Use $\sin 60^\circ = \cos 30^\circ = \frac{\sqrt{3}}{2}$ and $\sin 30^\circ = \cos 60^\circ = \frac{1}{2}$.

1. The DVM shown in the figure has a 200 kHz clock, and the integrator control waveform frequency is 45 Hz. Calculate the number of clock pulses that occur during $t_1$ and determine suitable time duration for $t_2$ when the input is 1 v. (10 Marks) \frac{200}{1999} = 0.10005 $T_R = t_1 + t_2$ $F_R = \frac{1}{T_R}$ $t_2 = \frac{1}{1999} = 5.002 \times 10^{-4} s \approx 0.05002 \text{ ms}$ $t_2 = 0.2 \text{ ms}$ $T_R = t_1 + t_2 \approx 0.25002$
