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)?

If a coffee filter is dropped, its velocity after t seconds is given by v(t)=4(10.0003t) feet per second. What is the terminal velocity, and how long does it take the filter to reach 99 of terminal velocity? Use a table increment of 0.1 and given your answer to the nearest tenth of a second.

A water tank is being drained and has the shape of a rectanuglar box 7m long, 6m wide and 5m high. How fast is the water depth changing when the water depth is 0.9m? V= 42(60-t)^2

A model rocket is launched straight up, with an initial velocity of 150 m/s. The height of the rocket can be modelled by h = -5t^2 + 150t, where h is the height in metres and t is the elapsed time in seconds. What is the maximum height reached by the rocket?
