Answer:

It is Z i believe.

Explanation:

Potential Energy = mass x gravity x height

W: 980 = (50)(9.8)(h)

X: 1029 = (35)(9.8)(h)

Y: 1519 = (62)(9.8)(h)

Z: 1176 = (24)(9.8)(h)

simplify:

W: 980 = 490h

X: 1029 = 343h

Y: 1519 = 607.6h

Z: 1176 = 235.2h

Divide from both sides of each equation:

W: (980/490) = h

X: (1029/343) = h

Y: (1519/607.6) = h

Z: (1176/235.2) = h

Simplify the left side:

W: 2 = h

X: 3 = h

Y: 2.5 = h

Z: 5=h
