Acar of mass 1800 kg is traveling east at 60 km/hr approaching an intersection. a large truck of mass 2400 kg is approaching the same intersection traveling north at 60 km/hr. after the collision, the car and the truck become tangled and move as a single object. assume that it’s a very slick road so that there is no friction between the vehicles and the ground. use only mks units.
is the collision between the cars elastic or inelastic?

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?
