Answer:
4m/s in the direction of the turn
Explanation:
The velocity of an object is the rate of change of its position with respect to a frame of reference.
Assuming the runner stays the same speed as he turns, his velocity will be 4m/s in the speed he turns.
Remember: energy is conserved in a chemical reaction (visualize the reaction and question whether heat lies on reactant side (left) or product side (right))
-exothermic- heat is released (heat is on the product side)
>forming an ionic lattice (SALT)- mixture of Na and Cl results in a more stable ionic lattice, causing this reaction to be exothermic
>burning wood
-endothermic- heat is absorbed (heat is on the reactant side)
> cooking an egg
