Starting from rest, a 0.0463 kg steel ball sinks into a vat of corn syrup. The thick syrup exerts a viscous drag force that is proportional to the ball's velocity. ?⃗ drag=−??⃗ where ?=0.292 N⋅s/m is a constant related to the size and composition of the ball as well as the viscosity of the syrup. Find the rate at which gravitational energy is converted to thermal energy once the ball reaches terminal velocity. P
For an incompressible fluid flow, velocity field and x and z components of velocity are given below. Derive the y-component of velocity. V(x,y,z) = u(x,y,z)i+v(x,y,z)j+w(x,y,z)k u(x,y,z) = –xy² + 2xz и w(x,y,z) = xy+y+3z
A ball with a mass of 3.7 grams and a diameter of 4.2 cm is hung vertically from the end of a string. A strong wind, travelling at a speed of 8.9 m/s blows past, causing the ball to hang at a nonzero angle with the vertical. Determine the angle that the ball will make with the vertical when it is in static equilibrium. Assume a drag coefficient of 0.45 for a spherical object and that the density of the air is 1.21 kg/m³.

Drag Force: A spherical particle of radius 5.9 cm and a mass of 229 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) 1 The position of the particle is given by x (t) = In (1+ bvot), where x is its position and t is the elapsed time.
