1. The problem statement, all variables and given/known data A parachutist of mass 70kg, in free fall at 136 km/h, opens a parachute. if the chute creates a 895 N air resistance force and the parachutist is being pulled down by a force of gravity at 686 N a) find hte acceleration of the parachutist b) how far does she fall in 5.0 s? 2. Relevant equations Fnet = ma, d = v1t + 1/2at^2 3. The attempt at a solution First i determined part A and i got the answer 3.0 m/s^2 [up]. which is correct in the answer key. then i used the equation d = v1t + 1/2at^2, converting 136 km/h to m/s d = v1t + 1/2at^2 d = 37.7 m/s(5s) + 1/2(3 m/s^2)[(5s)^2] and i got 226.4 m. the correct answer is 150m. i dont know what i did wrong. i then tried using the acceleration due to gravity, 9.81 m/s^2 because it is a freefall but the answer was still wrong. please help!!
