 Chapter 5 Practice Problems

 1

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?

 2

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?

 3

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

 4

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)?

 5

A 3000-kg satellite orbits the Earth in a circular orbit km above the Earth's surface (Earth radius = 6380 km, Earth Mass = 5.97x1024 kg).To the nearest Newton, what is the force acting on it?

 6

A 50000-kg shuttle orbits the Earth in a circular orbit km above the Earth's surface (Earth radius = 6380 km, Earth Mass = 5.97x1024 kg). To the nearest m/s, what is its speed?

 7

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?

 8

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?
