Do action and reaction cancel each other out?
galben [10]

Answer:

Action and reaction forces don't cancel each other out because they act on separate objects. ... Action and reaction forces are always equal in magnitude, so it's not possible to exert more force on an object than it can exert back.

CAN SOMEONE EXPLAIN HOW TO DO THIS?!?!

Both cars are canceling out the energy of each other. The energy that is left over because one car has a bigger kinetic energy is the energy that is going to move BOTH the cars.

First Car : <em>0.5 * 2000kg * 3m/s^2 = 10.24 KJ</em>

Second Car :<em> 0.5 * 2000kg * 2m/s^2 = 4 KJ</em>

Leftover Energy : <em>10.24 KJ - 4 KJ = 6.24 KJ
</em>
Movement of BOTH cars :<em /><em>
6.24 = 4000kg * v^2
</em>v =  √(6.24 / 4000) =0.04 m/s = 4 cm/s

In a lab experiment, two identical gliders on an air track are held together by a piece of string, compressing a spring between
ddd [48]

Answer:

Part a)

v_2 = -0.300

Part b)

Here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks

Explanation:

Part a)

As we know that there is no external force on the system of two gliders

So here we can use momentum conservation for two gliders

So we will have

m_1 v_1 + m_2 v_2 = (m_1 + m_2)v_i

m_1 = m_2

1.300 + v_2 = 2(0.500)

v_2 = -0.300

Part b)

now we will have

initial kinetic energy of both gliders is given as

K_i = \frac{1}{2}(m + m)(0.500)^2

K_i = 0.25m

Final kinetic energy of two gliders

K_f = \frac{1}{2}m(0.300)^2 + \frac{1}{2}m(1.300)^2

K_f = 0.89 m

so here final kinetic energy is more than the initial kinetic energy

This increase in kinetic energy is due to spring connected between them as the spring energy is converted into kinetic energy of two blocks
