The final velocity of skater 1 is 3.7 m/s to the right. The right option is O A. 3.7 m/s to the right.
<h3>What is velocity?</h3>
Velocity can be defined as the ratio of the displacement and time of a body.
To calculate the final velocity of Skater 1 we use the formula below.
Formula:
- mu+MU = mv+MV............ Equation 1
Where:
- m = mass of the first skater
- M = mass of the second skater
- u = initial velocity of the first skater
- U = initial velocity of the second skater
- v = final velocity of the first skater
- V = final velocity of the second skater.
make v the subject of the equation.
- v = (mu+MU-MV)/m................ Equation 2
Note: Let left direction represent negative and right direction represent positive.
From the question,
Given:
- m = 105 kg
- u = -2 m/s
- M = 71 kg
- U = 5 m/s
- V = -3.4 m/s.
Substitute these values into equation 2
- v = [(105×(-2))+(71×5)-(71×(-3.4))]/105
- v = (-210+355+241.4)/105
- v = 386.4/105
- v = 3.68 m/s
- v ≈ 3.7 m/s
Hence, the final velocity of skater 1 is 3.7 m/s to the right. The right option is O A. 3.7 m/s to the right.

Running on sand requires 1.6 times more energy spent than running on hard surface, so the force applied by our foot on sand is less.
funny of u to assume I have friends
If I remember anything from that part of my education (not great at physics) I'd say the answer is A, though I admit i'm not 100% sure
I dunno how to explain, once it hits that's the energy that was converting I guess.
Answer:
fem = -A β
Explanation:
Faraday's law gives the induced electromotive source (emf)
fem = 
the magnetic flux is
= B. A = B A cos θ
the bold are vectros. In this case the normal to the ring is parallel to the magnetic field so the angle is zero cos 0 = 1, also the area of the ring is constant
fem = -A 
we carry out the derivative of the function B = α + β t
fem = -A β
so we see that there is an electromotive force in the ring.
Answer:
c
Explanation:
the reason is that solids have a definite shape because of less energy moving they are still moving but liquids and gases move a lot more than a solid they are not ORDERED into position right it is because of the energy movement in the object.
