Question

Problem 19b

Answer 1

Given information

We are given that:-

The initial velocity when the torso begins to decelerate after the person lands on the ground, .(from the previous part of the problem)     

Final velocity when the motion stops, .      

Mass of the torso of the person,  and the distance it moves is .

 

 

Step-by-step explanation

Step 1.

Here, to find the deceleration we can use the kinematics equation;

 

Where is acceleration, is final velocity and is initial velocity. 

Substituting the known values, we get;
