Homework Statement
Bighorn sheep have extremely tough foreheads. A 200 pound bighorn sheep is running at 25 mi/h. (Converted to 91 kg.) He slams into his opponent and comes to a stop in 1 cm.(Converted to 0.01 m.) What force was exerted on his forehead?
Homework Equations
a=v[itex]^{2}[/itex]-v[itex]_{0}[/itex][itex]^{2}[/itex]/2Δx
F=ma
The Attempt at a Solution
Using the following equation I got an deceleration of -6050 m/s[itex]^{2}[/itex] Using F=ma, I got an answer of -550550 Newtons. This seems wrong, as the deceleration of a car going 100 mi/h is less than that. Where did I go wrong?
Thanks!
