An object of mass 700 kg is released from rest 1000 m above the ground and allowed to fall under the influence of gravity. Assuming the force due to air resistance is proportional to the velocity of the object with proportionality constant b=50 N-sec/m, determine the equation of motion of the object. When will the object strike the ground? (Hint: Here the exponential term is too large to ignore. Use Newton's method to approximate the time t when the object...

Question 2. Deep sea drones are used to explore the bottom of the ocean. The drone is allowed to sink using its weight force, however if the drone hits the ocean floor with a high velocity the operational camera will break. Hence the velocity of the sinking drone should be less than 4 m/s when hitting the ocean floor. The weight force is countered by drag and buoyancy (See Figure 1). Drag is directly proportional to velocity i.e. D =...
