Question

the worlds strongest man pulls a giant tire with a force of 2000 n. what is the magnitude (size) of the force pair? 0 > 2000 n < 2000 n 2000 n question 3 1 pts which one of the following objects has the greatest amount of momentum? a car parked along the side of the road. a turtle slowly crawling across the road. a stop sign warning cars to stop.

Explanation:

First Question (Force Pair Magnitude)

Step1: Recall Newton's Third Law

Newton's third law states that for every action, there is an equal and opposite reaction. The force the man exerts on the tire (action) has an equal - sized reaction force exerted by the tire on the man (the force pair).

Step2: Determine the Magnitude

Since the man pulls the tire with a force of 2000 N, the magnitude of the force pair (reaction force) is also 2000 N.

Step1: Recall the Formula for Momentum

The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass, and $v$ is velocity.

Step2: Analyze Each Option

• A car parked along the side of the road has a velocity $v = 0$, so its momentum $p= m\times0 = 0$.
• A stop sign is stationary, so its velocity $v = 0$, and its momentum $p = m\times0=0$.
• A turtle slowly crawling across the road has a non - zero velocity (even if small) and a non - zero mass. So its momentum $p = m\times v$ is non - zero, while the momentum of the parked car and the stop sign is zero.

Answer:

D. 2000 N (assuming the options are labeled as A. 0, B. >2000 N, C. <2000 N, D. 2000 N)
