Unformatted text preview: initial mass o± liq- Δ m= 0.4kg - 0.031kg= 0.369kg Problem 2) Rock B will reach a higher maximum height a±ter releasing, since they are launched ±rom identical springs ±rom the same displacement- so Δ PEs (rock B) = Δ PE s (rock A), which means they are launched with same amount o± Kinetic energy, Δ KE are equal. Also both rocks will have same Δ PEg while reaching their max heights, considering the systems closed. Δ PEg(rock B) = Δ PEg(rock A), but with Δ PEg= mg Δ h and mA > mB => h(rock B) > h(rock A).
