3.  In a football game a kicker attempts a field goal. The ball remains in contact with the kicker’s foot for 0.050 s, during which time it experiences an acceleration of 340 m/s2. The ball is launched at an angle of 51° above the ground. Determine the horizontal and vertical components of the launch velocity.

 

Because v0 is zero.  So the launch velocity magnitude is

 

 

Now use the launch angle q is 51° above horizontal (or ground) so our horizontal and vertical components are found to be:
