Question

The height, in feet, of an object shot upwards into the air with an initial velocity, in feet per second, of $v_i$, after $t$ seconds is given by the formula: $h = -16t^2 + v_it$ Use the equation above to answer questions about a model rocket is launched from the ground into the air with an initial velocity of 352 feet per second. Use the graph below to help answer the questions. H Height in Feet Starting Point Time in Seconds Highest Point Landing Point t Assessment Instructions Show and explain all steps in your responses to the following parts of the assignment. All mathematical steps must be formatted using the equation editor. Part 1: Create the equation for the height of the rocket after $t$ seconds. Part 2: Find the time it takes for the rocket to reach a height of 0. Interpret both solutions. Part 3: Find the time it takes to reach the top of its trajectory. Part 4: Find the maximum height. Part 5: Find the time it takes to reach a height of 968 feet. Round your answer to the nearest tenth.
