Answer: 34.4 sec
Explanation: Assuming that the desacceleration was constant, we have a = -1.5m/s²
vi = 186 km/h → 51.6 m/s
vf = 0 (because it stopped)
Vf = Vi + at
0 = 51.6 - 1.5t
1.5t = 51.6
t = 34.4 s
Answer:
the two beams must travel paths that differ by one-half of a wavelength.
“Intelligent Design” (henceforth ID) is the view that the universe gives evidence of being the product of an intelligent designer. As such it is a very old view. Certainly this was the position of the biblical writers (as Ps. 19:1, Rom. 1:18-20). Historically, many have articulated this position by means of the “teleological argument:” that when unintelligent beings act for a purpose, they must be under the control of a personal intelligence.
Continental crust plate name
Answer:
The ball is in the air for approximately 0.45 seconds
Explanation:
We only need to use the information on the height of the table to find the time, since the vertical movement is a movement under the acceleration of gravity, and with no initial velocity in the y-direction (recall that the ball rolls off a 1.0 m high table)
therefore the equation of motion for the vertical component is:
![y_f-y_i=\frac{1}{2}\, g\,t^2](https://tex.z-dn.net/?f=y_f-y_i%3D%5Cfrac%7B1%7D%7B2%7D%5C%2C%20g%5C%2Ct%5E2)
which for our information becomes:
![y_f-y_i=\frac{1}{2}\, g\,t^2\\1 = 4.9\,t^2\\t^2=\frac{1}{4.9} \\t=\sqrt{\frac{1}{4.9}} \\t\approx 0.45\,s](https://tex.z-dn.net/?f=y_f-y_i%3D%5Cfrac%7B1%7D%7B2%7D%5C%2C%20g%5C%2Ct%5E2%5C%5C1%20%3D%204.9%5C%2Ct%5E2%5C%5Ct%5E2%3D%5Cfrac%7B1%7D%7B4.9%7D%20%5C%5Ct%3D%5Csqrt%7B%5Cfrac%7B1%7D%7B4.9%7D%7D%20%5C%5Ct%5Capprox%200.45%5C%2Cs)
