In elastic
collision, both the kinetic energy and momentum are conserved. Conservation
means that both the kinetic energy and momentum will have the same values
before and after elastic collision.
<span>As the
object A has low mass than object B. Hence upon collision, object B moves
forward, while object A will move backward. So option "C" is correct. </span>
It is actually caused by the environment, so its false. :)
Answer:
velocity (v) =distance(s) ÷ time (t)
Explanation:
v=s÷t
s=v×t
s=3×3.4
s= 10.2m
Answer:
The larger pebble has 25 times more mass.
Explanation:
To solve the exercise it is necessary to apply the work and energy conservation equations.
For the case described, the work done must be preserved and must be the same, that is,

By definition work linked to the conservation of kinetic energy would be given by






The ratio between the mass and the velocity would be,



Therefore the answer is: The larger pebble has 25 times more mass.
I believe the answer you’re looking for is A. Spiraling around the source
