Question

two people collide on a busy city street. what information is needed to calculate the force one of the people exerts on the other person? (1 point) the speed of each person the location of the collision the velocity of each person the mass and acceleration of each person

Explanation:

Step1: Recall Newton's second law

Newton's second law states that \(F = ma\), where \(F\) is the force, \(m\) is the mass, and \(a\) is the acceleration.

Step2: Analyze each option

• The speed of each person (\(v\)) alone is not sufficient as \(F\) depends on \(m\) and \(a\) (not just \(v\)).
• The location of the collision is irrelevant to calculating the force.
• The velocity of each person (\(\vec{v}\)) alone is not enough as \(F = ma\) (not directly related to \(v\) without \(m\) and \(a\)).
• According to \(F = ma\), to find the force one person exerts on the other, the mass (\(m\)) and acceleration (\(a\)) of each person are needed.

Answer:

the mass and acceleration of each person
