A baseball player hits a ball 35 feet away and an outfielder catches it and throws it back to first base (25 feet away). What is the displacement of the baseball ball?
A. 60 feet displacement
B. 35 feet displacement
C. 10 feet displacement
D. 25 feet displacement
The displacement of an object is the difference between its final position and its initial position. In this case, the initial position of the baseball ball is where the player hit it, 35 feet away from the outfielder, and the final position is at first base, 25 feet away from the outfielder.
To find the displacement, we need to subtract the initial position from the final position: final position - initial position = 25 feet - 35 feet = -10 feet
Since the displacement is a measure of both distance and direction, the displacement of the baseball ball is -10 feet. Therefore, the correct answer is C. 10 feet displacement, as the negative sign indicates that the ball is in the opposite direction of the initial position.
