Acar of mass 2800 kg collides with a truck of mass 4000 kg, and just after the collision the car and truck slide along, stuck together, with no rotation. the car's velocity just before the collision was < 36, 0, 0> m/s, and the truck's velocity just before the collision was < -15, 0, 29> m/s. (a) your first task is to determine the velocity of the stuck-together car and truck just after the collision. (d) what is the increase in internal energy of the car and truck (thermal energy and deformation)?

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?
