(1 point) Supposed a body of mass 30 kg is falling in the atmosphere near sea level. Let v(t) m/s be the velocity of the body at time t in seconds. Assume that v is positive in the downward direction – that is, when the object is falling. We assume that the forces acting on the body are the force of gravity and a retarding force of air resistance with direction opposite to the direction of motion and with magnitude proportional to the square of the velocity. Let c be the constant of proportionality. The gravitational constant is g = 9.8m/s2 a) Find a differential equation for the velocity v: ap 9.8-((cv*2)/30) (b) Determine the limiting velocity after a long time. Your answer should be an expression in c. limiting velocity = sqrt(313.6/c) m/s (c) Find the drag coefficient, c, so that the limiting velocity is 42 m/s. C= 0.1482 kg/m

(1 point) Supposed a body of mass 30 kg is falling in the atmosphere near sea level.
Let v(t) m/s be the velocity of the body at time t in seconds. Assume that v is positive in the downward direction – that is, when the object is
falling. We assume that the forces acting on the body are the force of gravity and a retarding force of air resistance with direction opposite to the
direction of motion and with magnitude proportional to the square of the velocity. Let c be the constant of proportionality.
The gravitational constant is g = 9.8m/s2
a) Find a differential equation for the velocity v:
ap
9.8-((cv*2)/30)
(b) Determine the limiting velocity after a long time. Your answer should be an expression in c.
limiting velocity = sqrt(313.6/c)
m/s
(c) Find the drag coefficient, c, so that the limiting velocity is 42 m/s.
