Your forehead can withstand a force of about 6.0 kN before fracturing, while your cheekbone can only withstand about 1.3 kN. If a 140g baseball strikes your head at 30 m/s and stops in 0.0015 seconds, what is the magnitude of the balls deceleration? Express your answer in meters per second squared
I am mostly just wondering about finding the velocity B. I know how to find tension after that.
I got Vb= 4.214 m/s for the veloctity but I am not sure if I did it right.
Hight initial is 0.702 m
This was what I did
(1/2)(5)(2^2)+(5)(9.8)(.702)=(1/2)(5)(Vf^2)
