Explanation Given information: The given expressions are mass = ( 64000 ) ( 2000 ) / 32 slugs. Calculation: This is an application of Newton second law of motion which state that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. F = m a Suppose that the ship is moving in a forward direction then the force due to thrust is acting in such a way that it is pushing the ship forward and resistance of water is a frication force and always acts in the opposite direction of motion, Assume the mass of the ship is m and its acieration is a .Then we can write the equation of motion for the ship as F ︸ T h r u s t − D ︸ D r a g = m a Substitute the values in different quantities, ( a = d v d t ; k = 12 , 000 ) F − k v = m v ' v ' + k m v = F m This is linear first-order ODE which can be solved use the integrating factor method. If a differential equation is in the form. d v d t + p ( t ) v = Q ( t ) Integrating factor is μ ( t ) = exp ( ∫ P ( t ) d t ) and general solution is provided by, μ ( t ) y ( t ) = ∫ ( Q ( t ) ⋅ μ ( t ) ) d t + C Here, μ ( t ) = e ∫ k m d t = e k t m Calculate the general solution by substituting the value of integrating factor μ ( t )

A 800-lb object is released from rest 500 ft above the ground and allowed to fall under the influence of gravity. Assuming that the force in pounds due to air resistance is -20v, where v is the velocity of the object in ft/sec, determine the equation of motion of the object. When will the object hit the ground? Assume that the acceleration du to gravity is 32 ft/sec² and let x(t) represent the distance the object has fallen in t seconds. Determine the equation of motion of the object. x(t) =

Newton's law of cooling says that the temperature of a body changes at a rate proportional to the difference between its temperature and that of the surrounding medium (the ambient temperature), dT = -k (T – Ta) where T= the temperature of the body (°C), t = time (min), k = the proportionality constant (per minute), and Ta = the ambient temperature (°C). Suppose that a cup of coffee originally has a temperature of 70°C. Use Euler's method to compute the temperature from t = 0 to 20 min using a step size of 2 min if Ta = 20 °C and k = 0.019/min. (Round the final answers to five decimal places.)

Newton's law of cooling says that the rate at which a body cools is proportional to the difference in temperature between the body and an environment into which it is introduced. This leads to an equation where the temperature f(t) of the body at time t after being introduced into an environment having constant temperature To is where C and k are constants. Find the temperature of an object when t=9 if To = 17, C = 7 and f(t)= To + Ce k=0.6. - kt The temperature of the object is (Round to two decimal places as needed.)
