Below is the schematic of a ballistic pendulum. A projectile of mass m₁ is fired in to a large block of wood of mass m₂ suspended from a massless wire. m₂ is initially at rest. The projectile embeds in the block and entire system swings through a height h. Vo m₁ m2 (a) Use conservation of momentum the collision is given by. V₁ = O /m₁+m₂ m1 h to show that the speed of the block and the projectile combination just after vom 1 m₁+m₂ vo²m₁ 2 \m₁+ (c) Use conservation of mechanical energy to show that the initial speed of the projectile is given by Vo = m²) √2gh (b) Show that the kinetic energy of the system after the collision is given by K =
