A child throws a ball straight upwards to his friend who is sitting in a tree 18 ft above ground level.
a. If the ball leaves the child’s hand at a height of 2 ft with an initial speed of 40 ft/sec, write a function representing the vertical position of the ball s(t) (in ft) in terms of the time t after the ball levels the child’s hand,
(Hint: Use the model
b. Determine the time interval for which the ball will be more than 18 ft high.

The region of interest lies between x = 0 and x = 5, and y 0 and y = 5. Your tasks are the following: = 1. Analyze how the elevation changes with respect to x and y. To find the elevation changes, calculate the partial derivatives of the elevation function z with respect to x and 2. Calculate the total volume of soil above the 0-level (z region of interest. = y. 0). To do so, integrate z(x, y) over the wholearrow_forward
