1. The problem statement, all variables and given/known data A 4 kg book sinks a distance of 5m in the ocean starting from rest. The volume of the book is 0.00266666666666667 m^3. We assume the velocity of the Earth is zero during the whole process, and gravity and the bouyance force are the only interactions of the book. (Note: Take the density of sea water to be 1000 kg/m^3) Solving the problem using Newtons Seconds Law approach: (Assume standard coordinates, centered on the initial position of the book.) a) What is the net force acting on the book? F_x^(net) = 0 N F_y^(net) = ? N b) What is the acceleration of the book? a_x = 0 m/s^2 a_y = ? m/s^2 c) What is the final velocity of the book? v_x^(f) = 0 m/s v_y^(f) = ? m/s d) What is the final speed of the book? |(v^->^f)| = ? m/s 2. Relevant equations Fnet= F(gravity)+F(buoyancy) Fnet=ma F(gravity)=m*g F(buoyancy)=p(fluid)V(sub)g g=9.8 m/s^2 3. The attempt at a solution F(buoyancy)=1000*0.00266666666666667*9.8= 26.13 N (since it is a force against it'd be negative) F(gravity)=4*9.8=39.2 N Fnet^y= 39.2-26.13= 13.07 N It says my answer is wrong for Fnet^y. If I could just get the Fnet^y I can do the rest is there something I am missing?
