- Homework Statement
- A baseball with mass of m= 145g leaves a pitchers hand with a velocity of Vi = 46m/s.

If the pitchers arm moves through an angle of θ = 115◦, making an arch with radius of r= 55cm,what is the average force applied to the ball by the pitcher while she is throwing the ball? Note ,You can use the equation s = r θ for arclength as long as θ is in radians.

- Relevant Equations
- Average Force : F = m * (Vf – Vi) / t

Arclength : s = r θ

I've gone about getting the arclength S = 1.103m

The formula for average force is F = m * (Vf – Vi) / t

I know the mass and the initial velocity, but I don't know where arclength comes into play. I'm assuming Vf and T is referring to the moment that the ball leaves the pitchers hand, but I don't know how to go about solving those either.
