I have just a few homework problems that I just don't know where to start with at all. If there is anything anyone can do to push me in the right direction I would really appreciate it. I'm just not sure where to start on these. I have done a little work on some of them and come up with some guesses, but they are mostly that, guesses. Thanks in advance for any help at all. 16- A bridge that was 5 m long has been washed out by the rain several days ago. How fast must a car be going to successfully jump the stream? Although the road is level on both sides of the bridge, the road on the far side is 2m lower than the road on this side. a. 5 m/s b. 8 m/s c. 13 m/s d. 25 m/s I think im supposed to use the pythagorean therom for this, and I came up with an answer close to A, but it wasnt exact. so im not sure 18- A boat moves at 10 m/s relative to the water. If the boat is in a river where the current moves at 3 m/s, how long does it take the boat to make a complete round trip of 1000 m upstream followed by a 1000m trip downstram? a. 200 s b. 203 s c. 210 s d. 220 s Im pretty sure this one is D 220 s, but not totally positive. 29- Superguy is flying at treetop level near Paris when he sees the Eiffel Tower elevator start to fall (the cable snapped). His X-ray vision tells him Lois LaTour is inside and needs help. If Superguy is 1.0 km away from the tower, and the elevator falls from a height of 240m, how long does Superguy have to save Lois, and what must be his average velocity? (Superguy needs only touch Lois before she hits the ground because he is magically immune to the laws of physics and anyone he touches can also instantly become immune.) a 3 s, 333 m/s b. 5 s, 200 m/s c. 7 s, 143 m/s d. 9 s, 111 m/s I figure he has to travel 1028 m to get to her just before she hits, now do i need to calculate her terminal velocity? if so Im not really sure how to go about that, I missed a few classes and the book is a little unclear. 32- Wiley Coyote has missed the elusive road runner once again. This time, he runs off the edge of the cliff at 25 m/s horizontal velocity. If the canyon is 100 m deep, how far from the edge of the cliff does the coyote land? a. 112 m b. 225 m c. 337 m d. 400 m not sure where to begin at all with this one. 38- A ball is rolled off a table with an initial speed of 0.24 m/s. A stop watch measures the ball's trajectory time from the table to the floor to be 0.3 s. What is the height of the table? (neglect air resistance) a. 0.11m b. 0.22m c. 0.33m d. 0.44m everything i tried on this one I came up with nothing close to the answers, so i'm really not sure where to start.
