Tien Le 03/27/22 3:16 PM @ Test: Test 3 [Lessons 13-19] Question 4 of 19 This test: 38 point(s) possible This question: 4 point(s) possible Submit test Bob throws a ball straight up with an initial speed of 45 feet per second from a height of 7 feet (a) Find parametric equations that describe the motion of the ball as a function of time. (b) How long is the ball in the air? (c) When is the ball at its maximum height? Determine the maximum height of the ball (d) Simulate the motion of the ball by graphing the equations found in part (a). Assume Bob stands at horizontal position 0. and use g = 32 fusec/sec. =x(e) (Simplify your answer. Type an exact answer, using radicals as needed.) y = 0 Simplify your answer. Type an expression using t as the variable. Type an exact answer, using radicals as needed.) (b) The ball is in the air for about seconds (Round to two decimal places as needed.) (c) The ball is at its maximum height after |seconds (Round to two decimal places as needed.) The maximum height of the ball is |feet. (Round to two decimal places as needed.) (d) Choose the graph that represents the complete path of the ball through the air. (The graphs are displayed at x = 3 so that the vertical motion is easier to see and does not overlap the y-axis.)
