An object moves according to the distance (s) in feet, time (t) in seconds equation: Question list K s(0) = -81 +2391 + 530 Find the time to reach maximum height. Question 1 Find the maximum height. Question 2 Put your answer to two decimal places. The time to reach maximum height is seconds Question 3 The maximum height is feet. Question 4 Homework: Section 23.4 The HW Score: 30.94%, 4.95 of 16 E Derivative as a Rate of Change Question 2, Instructor- created question points Ho Points: 0 of 1 Save Find an expression for the instantaneous acceleration of an object moving with rectilinear motion according to the Question list K given function. The instantaneous acceleration of an object is defined as the instantaneous rate of change of the velocity with respect to time. Here, v is the velocity and t is the time. V = 812 - 5t +1 Question 1 Question 2 Question 3 Homework: Section 23.4 The HW Score: 30.94%, 4.95 of 16 Derivative as a Rate of Change Question 3, Instructor- created question points Ho O Points: 0 of 1 Save Find an expression for the instantaneous acceleration of an object moving with rectilinear motion according to the Question list K given functions. The instantaneous acceleration of an object is defined as the instantaneous rate of change of the velocity with respect to time. Here, s is the displacement, and I is the time. s =1 + 19t (Find v, then find a.)
