1. The problem statement, all variables and given/known data[/B] A 2.0 kg otter starts from rest at the top of a muddy incline 85 cm long and slides down to the bottom in 0.50 s. What net force acts on the otter along the incline? mass = 2.0 kg distance = 85 cm time = .50 s net force = ? 2. Relevant equations Fnet=ma I also used. V=x/t a=v/t 3. The attempt at a solution v=x/t 85/.5=170 a=v/t 170/.5=340 cm/s^2 340 cm/s^2 = 3.4 m/s^2 Fnet=ma (2.0 kg)(3.4 m/s^2)= 6.8 N The book says the right answer is 14 N though.
