There was a problem with other physics homework section so I just decided to write here. 1. The problem statement, all variables and given/known data H= 270m t1= 2.45s t3=7.35 V0=0 (freefall) t=7.35s t2= 4.90s g=10 We had to calculate the height what the body will be after 2.45, 4.90 and 7.35 s. 2. Relevant equations h=gt2/2 3. The attempt at a solution h1=30 h2= 120 h3= 270 So this is what it was supposed to look like. But, the answers in the book say that h1=30 h2=90 and h3= 150. Our teacher told us that it might be a mistake in the task by the authors. But he said that if we find a solution to the books answers then he will give the person +2 on the test ( this was a test task btw). So i could not think of anything since it does not make sense. I tried looking on the internet and i found this forum. If you have any ideas, please share them.
