2. A 55.0 kg Seth Cohen jumps from a dock into the 135 kg Summer Breeze (a boat),
which is at rest, on the west side of the dock. If Seth's velocity is 4.30 m/s to the west as
he leaves the dock, what is the final velocity of Seth and the Summer Breeze? (1.24 m/s
west)
please help

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?
