A fire tower at 295 degrees, B fire tower 255 degrees, 45 miles and 045 degrees from A, both spot the same fire. How far away is the fire from A? from B? The example problem has 180 - (60 + 40) = 80 Then a/sin40 = 60/80 b/sin60 = 60/80 a= 39.2 b=52.8, I can't figure out how they came up with those answers?

A ball is thrown from a building with the above formula.
at 1.5 seconds, the ball reaches its apex 100ft above the ground
at 4 seconds it hits the ground.

Is there a way to find initial height and initial velocity without using the derivative?

The book written by Mr. Bruce bolt says we should keep away from beaches if we sense earthquake. Tsunami may strike long after the shaking is stopped. I know the concept of Richter scale the long time of shaking of small amplitude also from large earthquake. Since I kept my quake alarm on unsecured wooden show case in first floor the amplification factor helped me to sense the feeble waves. That day was full moon day. The possibilities of raising the water will me more on that day in sea. I issued the warning like this “I have sensed very big earthquake which I have not heard in the history of earthquake. The sea water may rise to a great height. Therefore advice the people to be alert to move to a safer place in case of emergency." Don’t mistake that this instrument will give fore warning of earthquake or Tsunami. But this will sense all the earthquake waves from all the direction at all the angle when the force increases the set perfect limit by inbuilt calibration mechanism.

Calculate the acceleration for the follwing:

Initial Velocity: 0km/hour
Final Velocity: 24kn/hour
Time:3 seconds

Can someone explain how to sove it? I got 480m/s^2
What i did was change the 3 seconds to hours( .05 )
And dividing 24 by .05.

My teacher got 28,000km/s^2 I dont know who is right, me or her? HELP?

Can someone describe exactly how it works. Why do light coats let body heat out, whereas others don't. I hear it has something to do with convection within the jacket fibers.
