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?
