A škydiver weighing 170 lbf (including equipment) falls vertically downward from an altitude of 6000 ft and opens the parachute after 11s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.74 | v| when the parachute is closed and 11 |v| when the parachute is open, where the velocity v is measured in ft/s. Use g = 32 ft/s?. Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachete opens. v(11) = ft/s (b) Find the distance fallen before the parachute opens. x(11) = ft (c) What is the limiting velocity VL after the parachute opens? VL = ft/s

Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1 = 12 kg is on a horizontal, frictionless table and the other block with mass m2 = 7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. Solve for the magnitude of the acceleration, a1, of the block of mass m1, in meters per square second. Find the magnitude of the tension in the rope, T, in newtons.
