Question

I have a simple project due soon and I need your help. I recorded a slow motion video of my brother playing on a drum pad with two sticks with a stopwatch in the background. Given: he started at exaclty 5.07 seconds and ended at 14.78 seconds, and we know that the total amount of hits was 64. I'm trying to think of a good way I could use math to solve something. I was thinking about solving for either the velocity of how fast he was hitting or Beats per second. Can you solve either please? Show work for credit. I think the distance between the stick hitting the pad and the stick at the maximum raised height is 12 inches. I have to present this video with a question that I work through on the board so the class can solve it and I explain it. I need it by 4:45.

Explanation / Answer

The total time elapsed during playing on a drum pad by yor brother,

t = 14.78 s - 5.07 s = 9.71 s

The total distance travelled by stick for 1 round of druming,

  d = 2*(Distance between topmost and loswest position) = 2*12 = 24 inches

Since the total no of rounds of drumming, n = 64

So, the total distance travelled by stick in the whole process,

D = n*d  = 64*24 = 1536 inches

The speed of the drum stick during this process,

v = D / t = 1536 / 9.71 = 158.19 inches/s = 158.19*0.0254 m/s = 4.02 m/s
