Homework Statement
A Book (initially at rest) slides down an inclined plane, when it is at the bottom of the slope, its speed is 2.5 m/s. What is its speed half way and a third way down the slope.
V1 = 0
t1 = 0
V2 = 2.5 m/s
Homework Equations
a = [tex]\Delta[/tex]v / [tex]\Delta[/tex] t
v = [tex]\Delta[/tex]d / [tex]\Delta[/tex] t
Any of the other Uniform motion equations (kinematics)
The Attempt at a Solution
It looks simple, but i simply cannot figure out where to start...
I have to many missing variables, which unless i can assume something or equate 2 equations, i have no idea what to do.
I know for a fact that i am not suppose to be using forces (ex. x-component of acceleration due to gravity), i should be using kinematics.
