A 1.1 kg rubber ball is travelling at 2.0 m/s when it strikes a 3.9 kg rubber ball travelling at -1.9 m/s. If
the 1.1 kg ball rebounds at a speed of -2.5 m/s, what is the new speed of the 3.9 kg ball?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
