If Cory is walking at a velocity of 200 cm/s. He sees Ciara and with in 6 seconds he is running towards her at a velocity of 500cm/s. What is Cory’s acceleration?
500-200cm/s = 300cm/s / 6 s = 50 cm/s2

If I mix cold blue water with hot red water. At first the blue is on the bottom and and the red is on top. Why is this?
The blue is more dense because it's temperature is lower.
