From her second floor window 6 meters above the ground, Xiomara throws a tennis ball at a rate of 11 meters per second up towards her friend Itzagueri who is 12 meters above the ground. Assume a (t) = -9.8 meters per sec for the acceleration due to gravity. a. Assuming Itzagueri does not catch the ball, describe the motion of the ball 2 seconds after it was thrown. OHint (a): b. When does the ball reach its highest point? Xiomara OHint (b): c. Will the ball reach Itzagueri? Support your answer with calculations. Answer (c): d. Determine how high the ball is when it is falling at the rate of 5 meters per second. OHint (d) : e. Explain what So a(t) dt represents physically. OHint (e)
