1. The problem statement, all variables and given/known data You dive straight down into a pool of water. You hit the water with a speed of 7.0m/s, and your mass is 65kg. Assuming a drag force of the form Fd=(-1.40x10^4)v, how long does it take you to reach 2% of your original speed? (Ignore any effects of buoyancy.) 2. Relevant equations Fd=(-1.40x10^4)v Fg=mg Fnet=ma a=(vf-vi)/t 3. The attempt at a solution Fnet=mg-(-1.40x10^4)v a =(mg-(-1.40x10^4)v)/m a = -1500= vf-vi/t=0.14-7/t t= -6.86/-1500 t= o.oo46s When I enter this number or 4.6x10^-3, says it is wrong?? could someone help me, thisi s really frustrating me. The physics all seems to make sense to me.
