1. ### Some Questions Involving Newton's Law

Thanks, Ed Quanta. I hope it does. :)
2. ### Some Questions Involving Newton's Law

I don't know how to post pictures on here.... I did draw them tho... If I have a degree and a length, how do I turn that in to finding out time?
3. ### Some Questions Involving Newton's Law

A skier starts from rest at the top of a 24 degree slope 1.3 km long. Neglecting friction, how long does it take to reach the bottom? At what angle should oyu tilt an air table to simulate motion on the moon's surface where g= 1/6 m/s/s? A block is launched up a frictionless ramp that...
4. ### <b> Projectile Motion </b>

Any help for 51?
5. ### <b> Projectile Motion </b>

I started out drawing pictures and I can't get any farther... 50. In a very popular lecture demonstration, a projectile is fired @ a falling target. The projectile leaves the gun the same instant that the target is dropped from rest. Assuming that the gun is initially aimed at the target...
6. ### Projectile Motion of roller skates

For the second part I found the time to be 1.71s and Vf to be 71.42 m/s and Vi to be 45.83m/s all of this beinbg in the y-component. So the x-component would have t=1.17s and A= 0 but how would I find d or any velocities?
7. ### Projectile Motion of roller skates

Geoffjb, have you worked out this problem at all? Just wondering. :)
8. ### Projectile Motion of roller skates

Well I have for the coyote t=3.06s A= 15 m/s/s Vf=45.9 Vi=0 d=70 Roadrunner t=3.06 a=0 Vi=? Vf= ? d=70m Am i doing it right so far?
9. ### Projectile Motion of roller skates

4) The determined Wile E. Coyote is out once more to try to capture the elusive roadrunner. The coyote wears a new pair of Acme power roller skates, which provide a constant horizontal acceleration of 15 m/s2, as shown in Figure P3.73. The coyote starts off at rest 70 m from the edge of a cliff...
10. ### Tricky Problem

I have to make up or find a problem that invovles free fall velocity AND relative velocity!! Can anyone find/make up a problem for that? HELP!!!!
11. ### More Relative Velocity

I can't help but think maybe there's extraneous info?? Question: A rowboat crosses a river with a velocity of 3.30 mi/h at an angle of 62.5 degrees North of west relative to the water. The river is .505 mi wide and carries an eastward current of 1.25 mi/h. how far downstream is the boat when...
12. ### Homework help- Velocity!

I still can't get the right answer...
13. ### Homework help- Velocity!

Ok, here's the problem.. What am I doing wrong?? The pilot of an aircraft wishes to fly due west in a wind blwoing at 50 km/h toward the south. If the speed of the aircraft in the absence of wind is 200 km/h, in what durection should the aircraft head and what should its speed be relative to...
14. ### Velocity of kingfisher problem

Ok Thanks so much. I started out that way but I got stuck!
15. ### Velocity of kingfisher problem

So I can NOT understand what to even do first..... Please help me! A kingfisher is 30m above a lake when it accidentally drops a fish. A second kingfish 5m above the first dives toward the fish,. What's the initial speed it needs to catch the fish just before it reaches the water?
