Solve the differential equation below. Do NOT solve your answer for y. (223 – xy2 – 2y + 3) d.o+(2y – z'y – 21) dy = 0
2 Suppose Vf(x, y, z) - 2xyze i ze* j + ye k. If f(0, 0, 0) 1, find f(2, 2, 3).

y = 5 m y = 0 --- § ² ky = 223 N/m kz = 90 N/m 3. Two bowling balls, each with the mass of 7 kg, are dropped from 5 m above a pair of springs. The springs have the spring constants 223 N/m and 90 N/m, respectively. What will be the height difference in the two bowling balls' compressed positions? Assume that there's no air resistance.
