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 360 m/s2. The ball is launched at an angle of 46° above the ground. Determine the horizontal and vertical components of the launch velocity.

Answer 1

speed = a t starting from rest
speed = 360 * .05

u = speed * cos 46
v = speed * sin 46
