A rocket is used to place a synchronous satellite in orbit about the earth. What is the speed of the satellite in orbit?
I know that G= 6.67x10^-11 and the Mass of Earth is 5.98x10^24 kg.
So I'm to assume that I use the equation
v= Square root of([G*M]/radius)
But I don't know how...
What I gathered is that the roof tile has an initial velcity of zero, since the problem says it starts from rest.
The instantaneous velocity is the velocity the woman observes as the tile passes her window. I calculated this by dividing 1.4 meters by 0.19 seconds to get 7.36 m/s
I figured by...
A roof tile falls from rest from the top of a building. An observer inside the building notices that it takes 0.19 s for the tile to pass her window, whose height is 1.4 m. How far above the top of this window is the roof?
My train of thought is:
You are given the initial Velocity (Vo=zero...
A cab driver picks up a customer and delivers her 2.40 km away, driving a straight route. The driver accelerates to the speed limit and, upon reaching it, begins to decelerate immediately. The magnitude of the deceleration two times the magnitude of the acceleration. Find the lengths of the...
