Virginia beach is 100 kilometers wide and 30 kilometers long. if 2 cm of rain falls on virginia beach, how many cubic meters of rain fell on virginia beach?

Volume of a shape like that = width * length * depth

Volume = 100,000 m * 30,000 m * 0.02 m

Volume = 60000000 cubic meters

ek = (m.v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) v2/2

ek = (200 + 250) 2,32/2 = 450*5,29/2 = 1190,25 j
