Standing on a cliff that is 2000 feet above the ground, you want to throw a rock across a river which is 300 yards wide. 300 yards 2000 feet a. Convert 300 yards into feet. (1 yard = 3 feet) 300 yards = 900 feet b. If you throw the ball at an upward angle of 45 degrees, what does the initial velocity of the throw need to be for the ball to reach to the other side? Use the equation R= -, where R is the desired horizontal range, and vo is the initial velocity in feet per second. Round your answer to the nearest tenth. 169 feet per second R c. The formula h = = tells how high above the release point the ball will be at its highest point. How high above the ground will the ball you throw get at its peak? 2024.5 * f
