Homework Statement
[/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 = ?
Homework Equations
Fnet=ma
I also used.
V=x/t
a=v/t
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.
