Calculating Speed of Golf Ball After Contact

[jinman]

Homework Statement

i hit a golf ball of mass 0.045kg with an avg. Force of 2.5x10^3 N over a short time interval of 1.0 x 10^-3 s at an angle of 30 degrees with respect to the horizontal. neglect air resistance and assume a level course.

What is the speed of the ball immediately after contact?

Homework Equations

Ft=mv

The Attempt at a Solution

v=Ft/m

2500x.001/.045

v=55.6m/s?

If that is the wrong answer why? If that is right can someone further explain it to me?

It looks fine to me. What do you need explaining?

why would you think it's wrong?

Hrmmm. I thought it would be Harder. Thank you!
