A skydiver of mass 120 kg jumped from an aeroplane 3.5 km above the ground at timer seconds. After her parachute was opened, she experienced a frictional force of 100v with an initial velocity = 50 ms!. She moved a distance of 1.5 km before her parachute was opened. a) Show that acceleration of the skydiver is dv dt (50-63) (3 marks) b) Use separation of variables to find an expression for v in terms of t, where t is measured in seconds. (4 marks) It is safe to land when her speed is 13ms!. At what time I does she reach this speed? (3 marks) c)
