I'm not sure but it's probably C because you are treating a health problem.
Answer:
Opposite direction
Skeletal
muscles arise in antagonistic pairs where the muscles contract to produce
opposite movements at the same joint. Antagonistic muscles move a body part in
one direction by contraction, the other moves that part in opposite direction.
In
addition, when a muscle contracts to produced movement, its antagonist relaxes
to allow movement to take place such as biceps muscles is a flexor muscle for
elbow joint and triceps is the antagonist.
In order to calculate the gravitational force of the two bodies we use the formula which is expressed as:
F = GMm/R²
where <span>G = 6.67 x 10^-11 in SI unit, M and m are the mass of the two bodies and R is the distance between them.
F = </span>6.67 x 10^-11 (1.99×10^30) (6×10^24) / (1.50×10^11)²
F = 3.53×10^22<span>N</span>
A=<span>Δv/t
a=change in velocity/time (27 would be negative because it's decelerating)
So
</span><span>Δv=-27m/s
</span>t=5
-27/5=-5.4m/s^2
Final answer: -5.4m/s^2
Its C newtons 3rd law, because both the ball and the player are exerting a force. The ball is exerting a force on the player and the player is exerting a force to bring the ball to a rest or a state where it isn’t moving.
