Question 4 points) {#504496) {Projectile Motion) / {Non-Level Target} A baseball player wants to hit a home run over the wall of a stadium. The player swings the baseball bat so that it hits the ball when it is at a height of 0.941 m above the ground. The ball flies off at an angle of 30 above the horizontal and at a speed of 49.8 m/ s. What is the tallest wall that the player can clear (i.e., get the ball over) if the wall is 85.5 m away horizontally? Please enter a numerical answer below.
