Newton's 3rd law is "<span>For every action, there is an equal and opposite reaction"

a "cool" example to describe this might be how fish swim or the impact from someone throwing a football. </span>

<span>This law means that when one object exerts force on another, the same amount of force is exerted on the initial object, but in the opposite reaction. For example, when a billiard ball strikes another ball, the second ball is propelled forward. Simultaneously, the momentum of the first ball is slowed or stopped by opposing force. The amount that the first object is affected by the opposing force depends on the mass and motion of the second object.</span>

in an automobile crash, a vehicle was stopped at a red light is rear-ended by another vehicle. The vehicles have the same mass.

8 m/s

Explanation:

Using conservation of momentum :-

$m1u1 + m2v1 = m1u2 + m2v2$

Where:

m1 = Mass of first vehicle

m2 = Mass of second vehicle

u1 = initial speed of first vehicle

v1 = initial speed of second vehicle

u2 = Final speed of first vehicle

v1 = Final speed of second vehicle

From the received informations:

$m1 = m2$

$v1 = 0$

$v2 = u2 = 4 \frac{m}{s}$

$m1u1 + 0 = 4m1 + 4m1$

Now divide both sides by m1 :-

$u1 = 4 + 4$

$u1 = 8m/s$

Therefore, final answer is 8 m/s

Non examples of gravity ?

Afina-wow [57]

Floating. When you have no gravity you have nothing to be pushing you down to the floor so that would be an example of no gravity pushing on you.
