1. The problem statement, all variables and given/known data A sky diver of mass 83.0 kg jumps from a slow-moving aircraft and reaches a terminal speed of 46.0 m/s. (a) What is the acceleration of the sky diver when her speed is 30.0 m/s? 2. Relevant equations R=-bv mg-bv=ma 3. The attempt at a solution since R is the resistance force acting on the sky diver: R=mg therefore I set: 83*9.8 = -b(46), and solve for b, b = -17.683 then plug the same numbers back into mg-bv=ma to solve for the acceleration at 30m/s (83)(9.8)-(17.683)(30)=(83)a a = 3.41m/s^2 but this is not correct, can someone please tell me what i did wrong?
