Suppose the mass of a fully loaded module in which astronauts take off from the Moon is 11,900 kg. The thrust of its engines is 29,500 N. (Assume that the gravitational acceleration on the Moon is 1.67 m/s2.) (a) Calculate its magnitude of acceleration in a vertical takeoff from the Moon.   (b) Could it lift off from Earth? If not, why not? No, the thrust of the module's engines is equal to its weight on Earth. Yes, the thrust of the module's engines is equal to its weight on Earth.     No, the thrust of the module's engines is less than its weight on Earth. Yes, the thrust of the module's engines is greater than its weight on Earth. If it could, calculate the magnitude of its acceleration.

A skydiver weighing 178 lbf (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 17s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.76 |v| when the parachute is closed and 12 |v| when the parachute is open, where the velocity v is measured in ft/s. Use g = 32 ft/s². Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. v(17) = i ft/s (b) Find the distance fallen before the parachute opens. x(17) = i ft (c) What is the limiting velocity v after the parachute opens? VL = i ft/s

(a) What happens to the gravitational force between two objects if their separation is doubled? (b) Two objects with masses of m,= 5 kg and m2= 8 kg are connected by a light string that passes over a frictionless pulley, as in figure. Determine (i) the acceleration of each object, (ii) the tension in the string and (iii) the distance each object will move in 0.8 s of motion if both objects start from rest. m2
