Question

two students kick a soccer ball at the same time. student a kicks the ball with a force of 80 n to the right. student b kicks the ball with a force of 45 n to the left. calculate the net force.

Explanation:

Step1: Define positive and negative directions

Let right - direction be positive and left - direction be negative. So, $F_A = 80N$ and $F_B=- 45N$.

Step2: Calculate the net force

The net force $F_{net}=F_A + F_B$. Substitute the values: $F_{net}=80+( - 45)=80 - 45 = 35N$. Since the result is positive, the direction is to the right.

Answer:

B. 35 N Right
