Two blocks slide on a collision course across a frictionless surface, as in the figure. The resulting collision is inelastic. The first block has mass M = 1.00 kg and is initially sliding due north at a speed of Vi = 9.15 m/s. The second block has mass m = 7.20 ✕ 10−2 kg and is initially sliding at a speed of vi = 13.5 m/s directed at an angle θ = 27.5° south of east. Immediately after the inelastic collision, the second block is observed sliding at vf = 5.15 m/s in a direction of ϕ = 19.5° north of east. Determine the components of the first block's velocity after the collision. Vxf = m/s Vyf = m/s

Together, the bullet and block swing together away from the vertical. To what maximum angle from the vertical does the bullet and block swing before momentarily stopping? Neglect air resistance. Assume the string is massless, is 2.00 m long, and does not bend while it is swinging
