Answer:
D 50 newtons in a direction opposite to Ronaldo's force
Step-by-step explanation:
The factor -2 means the magnitude is doubled and the direction is opposite that of F. We know the magnitude of F is more than 24, so -2F will have a magnitude more than 48. The appropriate choice is ...
50 newtons in a direction opposite to Ronaldo's force
_____
You can recognize that the components of Ronaldo's force are the smaller numbers of the Pythagorean triple 7-24-25. That recognition tells you the magnitude of Federico's force is 2×25=50 N. Or, you can figure it out using the Pythagorean theorem:
|Federico's force| = √((-48)² +(14)²) = √(2304 +196) = √2500 = 50
