Answer:
i believe he threw the ball up at about 18 mph
Explanation:
Answer:
While In an <em><u>ideal/isolated</u></em> system, as long as the object is not in motion, its potential energy will be the same.
However, <u>potential energy is relative</u>. On Earth, usually, it is measured with respect to gravity. <u>The higher the object, the greater the potential gravitational energy</u>. It's all relative. For the sake of this question, I would assume that potential energy increases.
Explanation:
While kinetic energy depends upon speed, potential energy is always relative to some arbitrary reference point.

The maximum force of friction:
F = μ* N, where μ is the friction coefficient and N id the force of the doghouse normal to the surface.
N for a flat surface would be: N = m*g, where m is the mass and g is the gravitational acceleration = 9,81 m/s².
Combined:
F = μ * g * m
