Position of paul with respect to john is given as
14 m due west of john
position of George with respect to Paul is given as 36 m in direction 37 degree south of east
now we need to find the position of George with respect to John
so the magnitude is given as
and direction is given as
<em>so it is 26.2 m at an angle 55.75 degree South of east</em>
Answer:
42.11 years old
Explanation:
Given that:
In 2000, a 20-year-old astronaut left Earth to explore the galaxy; her spaceship travels at 2.5 x 10^8 m/s. She returns in 2040
To find her age we use:
Δtm is time interval for the observer stationary relative to the sequence of
events = 2040 - 2000 = 40 years
Δts is is the time interval for an observer moving with a speed v relative to the sequence of event
v = velocity = 2.5 x 10^8 m/s
c = speed of light = 3 x 10^8 m/s
Here age in 2000 is 20 year, therefore when she appear she would be 20 year + 22.11 year = 42.11 years old
Answer:
The centripetal force is provided by the x component of the Normal Force.
Explanation:
The centripetal force is a force that makes something to follow a cicular trayectory, this force is always oriented to the center of the circunferency-
So you can see in the image that i attached there is only two forces actting on the car, the normal force and the weigth, and as you can see the y component of the normal force cancels with the weigth, but the x component of the normal force (as it has nothing to cancel with) makes the car follow the circular trayectory so this is the centripetal force.
