We can use the law of conservation of energy to solve the problem.
The total mechanical energy of the system at any moment of the motion is:

where U is the potential energy and K the kinetic energy.
At the beginning of the motion, the ball starts from the ground so its altitude is h=0 and therefore its potential energy U is zero. So, the mechanical energy is just kinetic energy:

When the ball reaches the maximum altitude of its flight, it starts to go down again, so its speed at that moment is zero: v=0. So, its kinetic energy at the top is zero. So the total mechanical energy is just potential energy:

But the mechanical energy must be conserved, Ef=Ei, so we have

and so, the potential energy at the top of the flight is
Whatever distance north and then west you walked, you are then
(1.41 x that distance)
northwest of where you started.
As the temperature of water increases, the density of water will decrease.
Answer:
Explanation:
1760 yd/mi / 120 yd/field = 14⅔ fields/mi
A calorimeter measures the amount of heat in a chemical reaction. So the answer would be C, specific heat.
