How Much Force Did the Pitcher Exert on the Fastest Baseball Pitch?

[kaiazad]

Homework Statement

The fastest pitched baseball was clocked at 46 m/s. If the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1.0 m, and a baseball has a mass of 145 g.
What force did the pitcher exert on the ball during this record-setting pitch?

Homework Equations

f=ma

The Attempt at a Solution

I know that Newtons are (kg*m)/sec^2, but I only have a velocity, not an acceleration, so I can't figure out the right force.

I know that Newtons are (kg*m)/sec^2, but I only have a velocity, not an acceleration, so I can't figure out the right force.

Not to give away the answer: There is a formula that relates acceleration, initial velocity, final velocity, and distance traveled. Since you know three of the four items, with it you can find the acceleration, and hence the force.

Go find it in your textbook.

Figured it out! thanks!
