Solve the problem.An asteroid from deep space is sighted from the earth moving on a parabolic path with the earth at the focus. When the line from the earth to the asteroid first makes an angle of 90° with the axis of the parabola, the asteroid is measured to be 60 million miles away. How close will the asteroid come to the earth? Treat the earth as a point.
A. 6 million miles B. 3 million miles C. 9 million miles D. 30 million miles
Solve the problem.An object undergoes oscillatory motion about its equilibrium position according to the following functional relationship between its instantaneous displacement, f(t), and time, t:f(t) = ?2t - t3 -? ? t < ? ,where t = 0 marks a reference point in time that is not necessarily the beginning of oscillation.Find ao (if it is not zero), three nonzero cosine terms (if they exist), and three nonzero sine terms (if they exist) of the Fourier series for this description of motion.
A. f(t) = 3 + 12
B. f(t) = 3 - 12
C. f(t) = 12
D. f(t) = 12
Solve the problem.The capsize screening value C is an indicator of a sailboat's suitability for extended offshore sailing. C is determined by the function C = 4D-1/3B, where D is the displacement of the boat in pounds and B is its beam (or width) in feet. The International Offshore Rules require that the capsize screening value be less than or equal to 2 for safety. What is the maximum allowable beam (to the nearest inch) for a boat with a displacement of 
A. 13 ft 8 in. B. 71 ft 3 in. C. 27 ft 3 in. D. 6 ft 10 in.
