Answer:
Explanation:
The potential energy of an object is given by .
Recall that the weight of an object is equal to the force of gravity on the object. From this, we can set up the following equation and solve for the mass of the object:
Now we can plug in values to and solve:
.
Median plane - Sagittal plane through the midline of the body; divides the body or any of its parts into right and left halves.
Answer:
We know that ΔK = Kf - Ki = 1/2 m Vf^2 - 1/2 m Vi^2 = 1/2m(Vf^2-Vi^2) = 1/2 m ΔV^2.
The mass remains the same, just calculate the difference of squared velocities and multiply it by half of the mass.
