1. The problem statement, all variables and given/known data A certain freely falling object, released from rest, requires 1.65 s to travel the last 39.0 m before it hits the ground. (a) Find the velocity of the object when it is 39.0 m above the ground. (Indicate the direction with the sign of your answer. Let the positive direction be upward.) (b) Find the total distance the object travels during the fall. 2. Relevant equations v=v°+at a=v-v°/t distance Δx=vavg(t) 3. The attempt at a solution a) To find the velocity I am simply using the velocity formula, and making a=-9.8 because it is falling down. v=0+1.65s(-9.8)=-16.17m When I put -16.17 into the answer online it response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. I also tried -16.2, but before I use another try (I only have 3 left) I wanted to make sure that I am close to the answer, so I can try rounding to 16m/s. b) I am confused on this one but I got 47.1m and it tells me the same thing, that I am within 10% of the correct value.
