Homework Statement
Problem for physics project (How morce force does a person use on another's head in a punch, kick etc)
A 8lb medicine ball (to resemble a human's head weight) will be punched to accelerate X speed.
Homework Equations
(no clue what equations...)
d=Vi t + 1/2 at^2
d=vt
The Attempt at a Solution
I want to figure out the force required to do so.
So F=ma . I have m and i want to get F therefore i should figure out acceleration.
I have no clue on how to figure out acceleration.(Initial velocity?...)
I can get time and distance the ball will travel, (its like a half parabola problem)
