When you release the mass, what do you observe about the energy?

anygoal [31]

Explanation:

Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.

A 1,000 kg car is moving at 20 m/s, and slams into a building before coming to a halt.

Hi there!

We can calculate linear momentum using the following:
$\large\boxed{p = m v}$

p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)

Calculate:

$p = 1000 * 20 = 20000 kg\frac{m}{s}$

Now, we can relate force, time, and momentum with the following:
$\large\boxed{I = Ft}\\\\$

I = Impulse (kgm/s)
F = Force (N)
t = time (s)

Rearrange to solve for force:
$F = \frac{I}{t}$

The impulse is equal to the change in momentum. Since the car comes to a halt, all of its momentum is lost, so:

$I = \Delta p = p_f - p_i = 0 - 20000 = -20000$

Solve:
$F = \frac{-20000}{0.5} = \boxed{-40000N}$

**Negative force since the positive direction is towards the wall, and the negative direction is away from the wall.

A water filled ballon with an overall mass of 1 kg undergoes an acceleration of 2m/s squared. How much force is being applied to

Fudgin [204]

Force=mass x acceleration. F=1kg x 2m/s^2.

F=2 Newtons
