A glider is descending with a constant speed vo= 41 m/s and a constant descent rate of 1 m/s along a helical path with a constant radius R=400 m. Determine the time the glider takes to complete a full 360° turn about the axis of the helix (the z axis). (Round the Final answer to four decimal places.)

Applying principles of dynamics, with step by step solutions pls (i give 5 stars) A freighter is moving at a speed of 8 nautical miles per hour. The engines then had to be suddenly stopped. If it takes 10 minutes for the freighter to reduce its speed to 3 knots, determine the distance moved by the ship and its speed at the end of this interval. The deceleration of the ship is propor-tional to the square of its speed such that a = -kV^2.

Two radio transmitters positioned 400 mi apart along the shore send simultaneous signals to a ship that is 200 mi offshore and sailing parallel to the shoreline. The signal from transmitter S reaches the ship 200 microseconds later than the signal from transmitter T. The signals travel at a speed of 186,000 miles per second, or 0.186 mile per microsecond. Find the equation of the hyperbola with foci S and T on which the ship is located. (Hint: For any point on the hyperbola, the absolute value of the difference of its distances from the foci is 2a.) 200 mi Help me solve this C 400 mi Assume the origin is located at the midpoint of the foci.
