Answer:
Yes
Explanation:
The momentum of an object is given by:
where
m is the mass of the object
v is the velocity of the object
We know that an elephant has a mass much larger than the mass of an ant. However, we see that the momentum of the animal also depends on its velocity.
If the elephant is at rest, its velocity is zero:
v = 0
so its momentum is also zero:
p = 0
And therefore, an ant which is moving (so, non-zero speed) can have more momentum than an elephant, if the elephant is at rest.
Answer:
in the direction of the first body
Explanation:
Given:
- mass of the first ball,
- velocity of the first ball,
- mass of the second ball,
- velocity of the second ball,
<u>Now for the head-on inelastic collision:</u>
(since the bodies combine after an inelastic collision.)
in the direction of the first body. (Since the net result is positive as assumed in the equation for the first body)
Ok so light goes at a speed of <span>299,792 kilometers per second
so if my math is right 1.2 billion/299,792= 3335.646047926562 seconds
