Question

i have an incline problem where i'm given the vertical height from the base, the friction, the angle, it started from rest, and i already found the acceleration. Now how do i find its speed when it reaches the bottom??

Answer 1

There are two ways to do this:
- use kinematic equations
- use conservation of energy

The second of these methods is a little conceptually a little more complicated, so let's use the first.

With the first method, the object starts at rest. Now...
1. Find the length of the incline, s
2. Observe that the time, t, taken for the object to travel the distance, s, is given by
s = (1/2)at^2
3. Now use that time to find the velocity at time t, as
v = at

Answer 2

alrighty thankyou. that helped :)
