a satellite has a mass of 5850 and is in a circular orbit above the surface of a planet. the period of the orbit is 2.00 hours. the radius of the planet is what would be the true weight of the satellite if it were at rest on the planet's surface?
a 15-kg wagon is pulled to the right across a surface by a tension of 100 n at an angle of 30 degrees above the horizontal. a frictional force of 20 n to the left acts simultaneously. what is the acceleration of the wagon?

The same motor is used in rockets with different masses. The rockets have different accelerations. According to newton’s second law, how is acceleration expected to change as the rocket mass increases?.
in a solar system of $n$ planets, zorn the world conqueror can invade $m$ planets at a time, but once there are less than $m$ free worlds left, he stops. if he invades $13$ at a time then there are $6$ left, and if he invades $14$ at a time then there are $5$ left. if this solar system has more than $100$ planets, what is the smallest number of planets it could have?
Consider two spinning tops with different radii. Both have the same linear instantaneous velocities at their edges. Which top has a higher angular velocity?.
you construct a version of the cart and bucket in (figure 1), but with a slope whose angle can be adjusted. you use a cart of mass 183 kg and a bucket of mass 63.0 kg . the cable has negligible mass, and there is no friction. what must be the angle of the slope so that the cart moves downhill at a constant speed and the bucket moves upward at the same constant speed?
a car travels at 80 km/h on a level road in the positive direction of an x axis. each tire has a diameter of 66 cm. relative to a woman riding in the car and in unit-vector notation, what are the velocity at the (a) center, (b) top, and (c) bottom of the tire and the magnitude a of the acceleration at the (d) center, (e) top, and (f) bottom of each tire? relative to a
two crates, of mass 65 kg and 125 kg, are in contact and at rest on a horizontal surface. a 650 n force is exerted on the 65 kg crate. if the coefficient of kinetic friction is 0.18, calculate the (a) the acceleration of the system, and (b) the force that each crate exert on the other. (c) repeat with the crates reversed.
the large-scale transfer of material downslope under the pull of gravity is called . (enter only one word per blank.)
given that the wavelengths of visible light range from 400 nm to 700 nm, what is the highest frequency of visible light?
a rifle bullet with a mass of 12.0 g traveling toward the right at 260 m/s strikes a large bag of sand and penetrates it to a depth of 23.0 cm. determine the magnitude and direction of the friction force (assumed constant) that acts on the bullet.
