    Planet X has an equatorial radius of 6.00 107 m and a mass of 6.39 1026 kg. (a) Compute the acceleration of gravity at the equator of Planet X. 1 m/s2 (b) What it the ratio of a person's weight on Planet X to that on Earth? 2 (weight on Planet X / weight on earth) A stone has a mass of 5.0 10-3 kg and is wedged into the tread of an automobile tire, as the drawing shows. The coefficient of static friction between the stone and each side of the tread channel is 0.74. When the tire surface is rotating at 18 m/s, the stone flies out of the tread. The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. Assume that only static friction supplies the centripetal force, and determine the radius r of the tire.

  • What is the anwser to the physics question?

    The mass of a robot is 5410 kg. This robot weighs 3560 N more on planet A than it does on planet B. Both planets have the same radius of 1.33 107 m. What is the difference MA - MB in the masses of these planets?
