Practice Problems 

A plane is flying at 450 km/h in a vertical circle of
radius = km. If the plane
has a mass of 2000 kg, to the nearest Newton, what is the magnitude of the
force on the plane at the top of the circle? 





Four 1,000,000 kg masses are arranged in a square, meters
on a side. To the nearest ten thousandth of a Newton, what is the magnitude
of the force the mass in the lower left hand corner? 





What would be the force on a kg
mass put at the center of the square? 





A 2000 kg car rounds a curve with a radius of curvature of
60 meters at a speed of km/h.
What is its coefficient of friction (to 2 decimal digits)? 





A 3000kg satellite orbits the Earth in a circular orbit km
above the Earth's surface (Earth radius = 6380 km, Earth Mass = 5.97x10^{24}
kg).To the nearest Newton, what is the force acting on it? 





A 50000kg shuttle orbits the Earth in a circular orbit km
above the Earth's surface (Earth radius = 6380 km, Earth Mass = 5.97x10^{24}
kg). To the nearest m/s, what is its speed? 





If the moon's period is 27 days and its distance to the
(center of the) Earth is 384,000 km, what is the period, to the nearest hour,
of a satellite in a circular orbit with a radius of km?






If the Earth's period is 365.25 days and its distance to
the (center of the) Sun is one astronomical unit (AU), what is the period, to
the nearest day, of an asteroid in a circular orbit about the Sun with a
radius of AU?
