Does specific heat change with mass?

ch4aika [34]

Heat capacity ( C ) does change with mass. However, specific heat is the heatcapacity per unit mass ( c=Cm ). Therefore if you double the amount of mass in your system, you've doubled its heat capacity, but you've kept the specific heat the same. ... Specific gravity is another such quantity.

A bullet is shot vertically upward with an initial velocity of 128 ft/s. The bullet's height after t seconds is y(t) = 128t - 16

saul85 [17]

The height of the bullet when the velocity is zero is 256 ft.

<h3>Height of the bullet when the velocity is zero </h3>

The height of the bullet when the velocity is zero is determined by taking derivative of the function as shown below;

$v = \frac{dy}{dt} = 128 -32t \\\\when \ v \ is \ zero\\\\v = 0\\\\128 - 32t = 0\\\\32t = 128\\\\t = \frac{128}{32} \\\\t = 4 \ s$

The height of the bullet at this time is calculated as follows;

$y(4) = 128(4) - 16(4)^2\\\\y(4) = 256 \ ft$
