Question

select the correct answer.
eli and andy want to find out which of the two is stronger. eli pushes a table with a force of 120 newtons while andy pushes the table from the opposite side with a force of 125 newtons. ignoring the masses of eli and andy, what is the resultant acceleration of the table if its mass is 10.0 kilograms?
a. 13.5 meters/second²
b. 0.50 meters/second²
c. 4.0 meters/second²
d. 5.50 meters/second²
e. 1.35 meters/seconds²

Explanation:

Step1: Find Net Force

Forces are opposite, so net force \( F_{net} = F_{Andy} - F_{Eli} = 125\ N - 120\ N = 5\ N \).

Step2: Apply Newton's Second Law

Newton's second law: \( F = ma \), so \( a = \frac{F_{net}}{m} \). Substitute \( F_{net} = 5\ N \), \( m = 10.0\ kg \): \( a = \frac{5}{10.0} = 0.50\ m/s^2 \).

Answer:

B. 0.50 meters/second²
