Water is falling on a surface, wetting a circular area that is expanding at a rate of 10mm^2/sec. how fast is the radius of the wetted area expanding when the radius is 116mm?

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

explanation:

because god's plumb line “has a lot to do with the poor. it has a lot to do with righteousness that is living in right relationship with god and neighbor.
