An object at the top of a building with height 120 feet is thrown upward with an initial speed of 28 ft/s. Find its position z(t) above the ground t seconds after being thrown. (Use g = 32 ft/sec2.) z(t) = Find the time, in seconds, it takes for the object to hit the ground.
The velocity v (in feet per second) of a rocket whose initial mass (including fuel) is m is given by as attached, where u is the expulsion speed of the fuel, r is the rate at which the fuel is consumed, and g = 32 feet per second per second is the acceleration due to gravity. Find the position equation for a rocket for which m = 50,000 pounds, u = 12,000 feet per second, and r = 400 pounds per second. What is the height of the rocket when t = 100 seconds?

Using the information given in the image, find: d) the acceleration at any time (t) e) when it will hit the ground f) the velocity at which it will hit the ground
A researcher is nuning a simulation of an upward rocket to study the upward velocity of the rocket using various fuel consumption rates. The researcher has found that the upward velocity of the rocket can be represented by the following equation, mo v = u In gt Amo-qt. where v=upward velocity of the rocket (m/s), u= the velocity at which fuel is expelled relative to the rocket (m/s), m, = the initial mass of the rocket (kg), q = the fuel consumption rate (kg/s), g = the downward accelemation of gravity (m/s), and t = time taken by the rocket for the whole motion (s). If u = 1,500 m/s, m, = 125,000 kg, q = 2,300 kg/s and g= 9.81 m/s are the values used by the researcher in one of his simulations, estimate the time, t at which v = 680 m/s using False Position method. It is known that the time, t is somewhere between 15 s and 35 s. Perform THREE (3) iterations only and calculate the approximate percent relative error, Ea| for every iteration.
Two people are riding in a motorboat and the combined weight of individuals, motor, boat and equipment is 640lb The motor exerts a constant force of 20 lbs on the boat in the direction of motion, while the resistance is numerically = to one and a half times the velocity v( in ft/second) if the boat started from rest,find the velocity of the boat after 40 seconds
