Answer: 1.77 s
Explanation: In order to solve this problem we have to use the kinematic equation for the position, so we have:
xf= xo+vo*t+(g*t^2)/2 we can consider the origin on the top so the xo=0 and xf=29 m; then
(g*t^2)/2+vo*t-xf=0 vo is the initail velocity, vo=7.65 m/s
then by solving the quadratric equation in t
t=1.77 s
Answer:
Explanation:
Refer the schematic for explanation.
According to the given condition the first cyclist covers 1080 meters eastwards and then travels 1430 meters northwards to reach the camp.
But the second cyclist travels 1950 meters northwards therefore he travelled 520 meters more in the north than the first cyclist.
<u>So, according to the schematic we find the distance DC in the triangle DCE using Pythagoras theorem:</u>
Answer: California
Explanation:
The Big Dipper has eight stars in it. Seven are visible at a glance, while the eighth is a visible double star that is just detectable with the naked eye in an area with clear "seeing" and with good vision.
To first observe an easily recognizable change in the shape formed by these stars (to an observer without a telescope), someone can look high in the sky toward the northeast at a certain time of the year and you can't miss the Big Dipper at around 8 p.m from mid-northern latitudes which is California
D. The net gravitational force on the astronaut is not balanced by a normal force
