A satellite completes one revolution of a planet in almost exactly one hour. At the end of one hour, the satellite has traveled

2.0 × 10 7 meters and is only 10 meters away from its starting point. What is the numerical value of the satellite's average velocity after that one hour?

You haven't described the shape of the orbit. 
Fortunately, it doesn't matter.

Average speed = (distance covered) / (time to cover the distance)

                           =  (2.0 x 10⁷ meters) / (1 hour)

                           =     2.0 x 10⁷ meters/hour

                           =     5,555 and 5/9 meters/second .

Note that this is the satellite's speed. 


Regarding velocity:

           Velocity = (displacement) / (time for the displacement)

                         =  10 meters/hour

                         =  0.002777... meters/second  (rounded)

                             in the direction from the starting point
                             to the location after that one hour.

svetlana [45]

Answer:

35.1688 seconds

Explanation:

M = Mass of sphere = 8200 kg

R = Radius of sphere = 90 cm

F = Force = 30 N

Moment of inertia is given by

I=\dfrac{2}{5}MR^2\\\Rightarrow I=\dfrac{2}{5}\times 8200\times 0.9^2\\\Rightarrow I=2656.8\ kgm^2

Torque is given by

\tau=I\alpha\\\Rightarrow FR=I\alpha\\\Rightarrow \alpha=\dfrac{FR}{I}\\\Rightarrow \alpha=\dfrac{30\times 0.9}{2656.8}\\\Rightarrow \alpha=0.01016\ rad/s^2

For one rotation

\theta=\omega_it+\dfrac{1}{2}\alpha t^2\\\Rightarrow 2\pi=0\times t+\dfrac{1}{2}\times 0.01016\times t^2\\\Rightarrow t=\sqrt{\dfrac{2\pi2}{0.01016}}\\\Rightarrow t=35.1688\ s

The time taken to rotate the sphere from rest is 35.1688 seconds

Two bricks are released at the same time from the same point ten feet above the ground. One of the bricks is falling straight do
natita [175]
Both bricks will hit the ground at the same time.

Falling vertically is always accelerating at 9.8 m/s² because of gravity.
Nothing that's happening horizontally has any effect on that.
The brick that happens to have some horizontal motion will 
probably hit the ground way over there, but that will still be
at the same TIME as this one.

This is a perfect place to remind you of the old unbelievable story,
which I'll bet you heard before:

If you fire a bullet horizontally from a gun, and at the exact same
moment you DROP another bullet out of your hand next to the gun,
the two bullets will hit the ground at the same time !  Even though
they'll be far apart.

Horizontal speed has no effect on vertical behavior.
