The mass of a truck with its cargo is 1800 kg. the truck is coasting to the right with a speed of 10 m/s. as it coasts its cargo of mass 300 kg is lifted up out of the truck by a crane. what will the velocity of the truck be after its cargo is taken off?

During this chemical reaction energy is released. in the chemistry lab, this would be indicated by an increase in temperature or, if the reaction took place in a test tube, the test tube would feel warmer to the touch. reactions like this release energy because a) the reaction requires activation energy. b) the reactants have less potential energy than the products. c) the reactants have more potential energy than the products. d) the mass of the products is greater than the mass of the reactants.
