If a ball is thrown vertically upward from the roof of 4848 foot building with a velocity of 6464 ft/sec, its height after tt seconds is s(t)=48+64t−16t^2  What is the maximum height the ball reaches?   What is the velocity of the ball when it hits the ground (height 0)?

A body is projected vertically upward such that is height from the ground in feet is h = 50t – 16.1t^2 where t = time in flight in seconds.  After how many seconds will the velocity be 12 fps?

By using equation qx= 2mx/(2+mx) , derive a similar equation for the more general case of an age group of width years (x to x+n years) that is show tha nqx = (2*n* nmx) /(2+n*nmx)

You shoot an arrow in the air. It falls to earth. Its height (in feet) after t seconds is "h(t)=80t−16t^2. What is its velocity as it hits the ground?

Suppose an equilateral triangle has edges of lengths x. As the lengths of the edges increase, the area increases by V .square centimeters per minute. At what rate is = 5 , -- centimeters per minute. Write the length of the edge changing when each edge is 5 centimeters? At the length of each edge is increasing by the number below and round the solution to the nearest ten thousandths of a centimeter.

The speed of a viral post is modeled by the function, Γ ( t ) = 3 squareoot 2t + 8e^t. If t is the number of hours passed since the initial posting, and Γ is the number of people (in thousands) per hour, how many people have seen the post from the initial post to hour eight?
