Question

A soccer player kicks the ball toward a goal that is 29.0m infront of him. The ball leaves his foot at a speed of 19.0m/sand an angle of 32.0o above the ground. Find thespeed of the ball when the goalie catches it in front of thenet. (Note: the answer is not 19.0m/s) answer: 17.8m/s A soccer player kicks the ball toward a goal that is 29.0m infront of him.

Explanation / Answer

   angle (theta)    = 32 o    initialvelocity u = 19 m/s    R =u2 sin (2x32 ) / g    u2 = Rg / sin 64    = 29 x9.8 / 0.898    =316.2014    u = 17.78m/s
      initialvelocity u = 19 m/s    R =u2 sin (2x32 ) / g    u2 = Rg / sin 64    = 29 x9.8 / 0.898    =316.2014    u = 17.78m/s
