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