I think it would be velocity bc the formula for kinetic energy is 0.5mv^2 (which involves velocity) and the formula for potential energy is mgh (which doesn't involve velocity).

An object with a kinetic energy of 1125J has a<br> mass of 250kg. What is its velocity?
Elena-2011 [213]

Answer:

3 m/s

Explanation:

Kinetic energy of a body is given by the formula K= {1\over2} m v^2. Let's replace everything we have and solve for what's left.

1125J = {1\over2}\cdot 250 kg \cdot v^2

v^2 ={ 1125 \cdot 2 \over 250}} or v= 3 {m \over s}

You drop a stone down off a bridge. You are able to count to 4.0 seconds when it finally hits the water. How high is the bridge?
mart [117]

Answer:

The height of the bridge is 78.4 m.

Explanation:

Given;

time of the stone motion off the bridge, t = 4.0 s

acceleration due to gravity, g = 9.8 m/s²

The height of the bridge is given by;

h = ut + ¹/₂gt²

where;

u is the initial velocity of the stone, u = 0

h = ¹/₂gt²

h = ¹/₂(9.8)(4)²

h = 78.4 m

Therefore, the height of the bridge is 78.4 m.
