They do because if one thing is moving and the is there both moveing in once
We have that the Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel
From the Question we are told that
You toss a ball to someone one meter away
You toss it to someone four meters away
Generally
When you toss toss a ball to someone one meter away and You toss it to someone four meters away the are things that have changed
Therefore
The Throw has changed in distance the ball has traveled and the Force applied in trowing the ball and Possibly the time of travel

Momentum is Mass × Velocity
= 1875×22 = 41250 kg m/sec
F = ma
We have mass = 20kg
And we need to solve for acceleration
So acceleration is change in velocity over time, in this case we have one velocity and we can assume the man started from rest so
12.3 / 0.9 = a
a = 13.6667
Now we can plug that into F = ma
F = (20)(13.6667)
F = 273.334
Rounding
F = 273.33
Now he is traveling east so we need a force towards the rest, or in the opposite direction to stop his motion.
If we assume east is the positive direction then we need a force of
-273.33 N to stop the man or 273.33 towards the west.
Answer:
75
Explanation:
i am not sure but if 200N boy is being held back then the force that's holding him back must be equal to or greater than his weight. if 125N is already exerted then the tension will be:
T=200-125
= 75
