Answers Latest Version Top Rated
A+
A flatbed truck carrying a light box makes a sharp turn and
the box slides off the truck bed. In what direction will the box
slide?
along the tangent to its circular path
A 1.2 kg rock is swung around on a string in a vertical circle
with a radius of 0.85 m. The minimum speed required for the
rock at the top of the circle to keep it in it's circular path is
2.9 m/s
If the distance between two masses is doubled, what
happens to the gravitational force between the masses?
It will be reduced to one quarter (Fg=1(1)(1)/2^2=1/4)
NASA is launching a satellite with mass m into a circular
orbit with radius r around the Earth. The orbit of the satellite
is illustrated in the figure below(LOOK AT NOTES). The
velocity, v, of the satellite is shown with the arrow. Consider
the following arrows and directions (AGAIN LOOK AT
NOTES)
-Which arrow is in the direction of the net force on the
satellite?
D. IV
If a second satellite is placed in a larger circular orbit than
the first, how will the speeds of the satellites compare?
the second satellite must have a smaller speed.
The satellite does not fall down to the earth because
they have a sufficient horizontal speed to move around the earth
instead of falling down,
A student sets up a meterstick resting on a stand at the 80-
cm mark and held in place by a scale attached at the zero cm
