Need help with ticker tape

[madoscar65]

Does anyone know how to find the accerleration on a ticker tape??

We know that

To find the final velocity, v, take the distance between last 6 dots (5 spaces equivalent) divided by 0.02s x 5.
Likewise, you can take the distance between last 7 dots divided by 0.02s x 6.

To find the initial velocity, u, use the same method as above, but take the distance between the first 6 dots, divided by 0.02s x 5.

Time = t = (Total no. of dots - 1) x 0.02s

Substitute the values into the formula and viola, there your go!

How do we get 0.02 you ask, since the ticker-tape has a frequency of 50 Hertz, it makes 50 dots in one second. Hence, time to make one dot would be s. Time to make say, 6 dots, would be 0.02s x 5. (You don't count the first dot because that's the starting point and there is no distance travelled.)
