F = ma
6.25 N = 0.4 kg · a
a = (6.25/0.4) m/s² since N=kg·m/s²
a = 15.625 m/s²
The answer is c) 15.6 m/s²
(Note that the mass of the soccer player is irrelevant.)

◦•●◉✿What does E mc2 actually mean?
E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.✿◉●•◦
The two forces acting on the object would be 1. Weight because of gravity pulling the object toward the ground and 2. Drag resisting this motion
Answer:
77.35 m / s
Ф = -17° from + X axis or 343° from + X axis
Explanation:
v1 = 75 m/s 25° east of north
v2 = 100 m/s 25° east of south
Write the velocities in vector form ,we get
Now add the velocity vectors to get the resultant of the velocities.
magnitude of resultant velocity is 
= 77.35 m / s
The direction is Ф from X axis
Ф = -17° from + X axis or 343° from + X axis
