Question

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.

Answer 1

Since average a= delta v/ delta t
340(.05)= delta v
v=17 m/s
Furthermore this launch velocity has the angle of 51 degrees. You then use your handy dandy trigonometric skills to find the horizontal and vertical components of the launch velocity.

17cos(51)= horizontal
find the vertical?
