A bullet with mass m and velocity ViA = v is fired horizontally toward a wooden block with mass m = 5m that is hanging from strings as a ballistic pendulum. The bullet reverses its direction and has speed V2a = v/2 after the collision as shown in the adjacent Figure. a) Find the speed Vs of the block just after the collision. Is the collision between the bullet and the block elastic or inelastic? (You must show your work to receive any credit). Explain. Using energy considerations, find the maximum height h to which the block rises after the collision. If this collision lasted t units of time, find the magnitude and direction of the average force exerted by the wooden block on the bullet. Express your answers in terms of any or all of the variables v, m, t, and g (acceleration due to gravity). hmax = V^2 / (2g) (a) F = M (Bullet-System) + M (Block-System) k++ = +ug operating mass = m EFe = hu = mghmax mB = 5m J = F VAL = 29 MAV J = F6 SP AW mv + 5m = 06 DE 2 P2 - P 2mv mv = mv DE mv - mv 2 2 2 Sw = 10 5m Ym = mv 5m oF Block Systemalter Collisio -mv 10 Fava 2 (n) 100 -mv Favg = 26 Svv2 6v2 = 4 20 C 20 20 m = m + 5m KE was lost by a fudof 27 of/2onelashc (mv)^2 / 5 = 100 Page 6/7

5. A particular monument is a solid sphere of radius 1.7m and mass 200kg that's free to rotate about an axis through its center. The monument is initially at rest until a tourist applies a constant force of 15N at the equator of the sphere perpendicular to the radius. (The moment of inertia of a sphere rotating about a line through its center is $(\frac{2}{5}) \text{?} \text{?} \text{?} \text{?} \text{?} m^2)$ a. What is the angular acceleration? b. What is the angular displacement during the 1.5 minutes?

The input to the AC circuit is a source voltage $v_s(t)$ with amplitude of 12 V, frequency 10 rad/s, and a phase angle of $0^\circ$. Thus the phasor corresponding to the given $v_s(t)$ is respectively described as $V_s(\omega) = 12\angle 0^\circ$. The impedances corresponding to each circuit element are: $Z_{R_1}(\omega) = 4\Omega$, $Z_{R_2}(\omega) = 16\Omega$, $Z_{L_1}(\omega) = j20\Omega$, $Z_{L_2}(\omega) = j25\Omega$, $Z_C(\omega) = -j14\Omega$
