Answer:
The two skaters will move with a common speed of 1.19 m/s.
Explanation:
Given that,
Mass of Alex,
Initial velocity of Alex,
Mass of Barbara,
Initial velocity of Barbara,
After the collision, the two skaters move together at a common velocity. Let V is the common velocity. Using the conservation of momentum as :
Magnitude of final velocity:
So, the two skaters will move with a common speed of 1.19 m/s.
"Force and distance" are the ones among the following choices given in the question is the relationship that the inverse square proportionality in Coulomb's equation explain. The correct option among all the options that are given in the question is the third option or option "c". I hope the answer has helped you.
You will use candela for comparing.
