Homework Answers
Solve that for g using algebra. Since in mgh g is multiplied by m and h, do the opposite: divide mgh by m and h. And remember that what you do to one side of an equation you must do the other side as well.

When a manganese bar of mass m is dropped through a height difference Δh, its potential energy changes by the amount mgΔh, where g is the acceleration of gravity, equal to 9.81 m s-2. Suppose that when the bar hits the ground, all that energy is converted to heat, increasing the temperature of the bar. If the specific heat capacity of the material in the bar is 0.479 J K-1 g-1, calculate the height from which the bar must be...

Calculate the velocity and the propagated uncertainty in the
calculated velocity due to the uncertainty in the height and the
acceleration due to gravity.
Problem 1 In an experiment kinetic energy is changed to potential energy with negligible loses so the initial height is related to the maximum velocity. Assuming the minimum height is zero, the maximum velocity can be found using mgh 1/2mv2 vis the velocity. Ifg at that location is known to be 9.792 0.011 m/s2 and h...
