Question
m TIL) An object with mass 26kg is in free fall. It has two forces acting on it: gravity and air resistance. For this model we will take the ground to be at height 0, the height of the object to be y(t) meters from the ground, and the acceleration due to gravity to be -9.81- We want to set up a differential equation for the forces acting on the object. The force due to gravity is is given by mass times acceleration acting in the opposite direction of y. The force due to air resistance is proportional to the square root of the velocity of the object in the same direction is y. The constant of proportionality for the wind resistance has been measured at 0.2. Find the differential equation that models the displacement of the object y at time t. = 0 If the object is dropped from a height of 12 the IVP is y(0) = y'(0) = Note: use y,y', etc instead of y(t), y'(t) in your answers. After you set up your differential equation you will have to set it equal to zero so that WeBWorK will understand your answer, do this in a way so that the highest order derivative has a positive coefficient.
