the rocket (in meters) t seconds after launch is given by h(t) = 10t² A videographer is documenting the event from 100 meters away. As the rocket rises, the camera angle must change accordingly to document the flight. Let 0(t) be the angle of the camera t seconds after launch. Before launch, when the rocket is sitting on the launch pad, the camera is perfectly level, so 0(0) = 0. After t seconds, how fast is the camera angle changing in order to keep the rocket in the shot? (Include units in your final answer). 10 t? 100 m
The deck of a bridge is suspended 285 feet above a river. If a pebble falls off the side of the bridge, the height, in feet, of the pebble above the water surface after t seconds is given by y = 285 − 16t2. (a) Find the average velocity (in ft/s) of the pebble for the time period beginning when t = 2 and lasting the following amount of time. (i) 0.1 seconds (ii)0.05 seconds (iii)0.01 seconds (b) Estimate the instantaneous velocity (in ft/s) of the pebble after 2 seconds.
30t Z'(t) = + 2t (3t2 + 6.05) where t is time in days since the Zombie horde was accidentally released from the research facility, and Z represents the total number of Zombies loose. There were 30 Zombies accidentally released from the facility at the start of the outbreak (t = 0). a. Find the function that represents the total number of Zombies on the loose at any given time. b. How many Zombies will there be after 3 weeks? That is, 21 days?
The amount of growth of plants in an ungrazed pasture is a function of the amount of plant biomass already present and the amount of rainfall.t For a pasture in the arid zone of Australia, the following formula gives an approximation of the growth. Y = -55.12 - 0.01535N - 0.00056N? + 3.946R Here Ris the amount of rainfall, in millimeters, over a 3-month period, Nis the plant biomass, in kilograms per hectare, at the beginning of that period, and Y is the growth, in kilograms per hectare, of the biomass over that period. (For comparison, 100 millimeters is about 3.9 inches, and 100 kilograms per hectare is about 89 pounds per acre.) Now we consider the amount of growth Y as a function of the amount of plant biomass N already present. (a) First we assume that the rainfall is 80 millimeters, so R = 80. (1) Find a formula for the growth Y as a function of the amount N of plant biomass already present. kg/ha (ii) Make a graph of Y versus N. Include biomass levels N from 0 to 800 kilograms…
