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.
