Find the velocity of point A and the angular velocity of link 3. Given: ( v_B = 40 ) m/s, ( r_AB = 400 ) mm, scale: 1 cm = 0.1 m (pos), 1 cm = 5 m/s (vel)
a) ( v_A = 4 ) m/s, ( ω₃ = 8 ) rad/s
b) ( v_A = 5 ) m/s, ( ω₃ = 10 ) rad/s
c) ( v_A = 8 ) m/s, ( ω₃ = 12 ) rad/s
d) ( v_A = 10 ) m/s, ( ω₃ = 14 ) rad/s
