Ok, I've been running over this problem for about an hour now, and I can't figure out where I'm going wrong. I'm a complete newb, so I'm sure it's something stupid, but I could use the help.
An object with an initial velocity undergoes constant acceleration. Position information was collected at 4 poins and is shown in the table. Using Yn+1 - Yn = Vnt + (1/2)ayt2 determine the acceleration and fill in each box.
edit : it screwed up my table, I hope it makes sense.
Point #; Time (s); Position (m); Average Acceleration (m/s2
1; 0; 1; n/a
2; 1; 8; (answer here)
3; 2; 25; (answer here)
4; 3; 52; n/a
Yn+1 - Yn = Vnt + (1/2)ayt2
Here's one attempt I tried.
25m - 8m = 7(1) + 1/2ay(1)
ay = 20
I've tried a few different attempts, I'm not sure I should show them all here. The problem I'm running into is that I think I need to plug in velocity figures, but I wasn't given any, so I messed around some, but the answers don't make sense, and aren't uniform.
