Rotation Quiz Part 2 Physics 1180 MC² Name: 1. A 0.50 kg mass is whirled around at the end of a 0.81 m string. The mass sweeps out a horizontal circle. The string has a 20 N capacity, what is the maximum tangential speed of the mass if the string doesn't break? 2. A 3,000 kg truck rounds an unbanked curve with a radius of 85.0 m at a speed of 15.0 m/s. What minimum coefficient of friction must exist between the road and tires to prevent the car from slipping? 3. An object of mass 10.0 kg is transported to the surface of Planet Z where an objects weight is 15.00 N. The radius of the planet is 5.0x 10³ m. What is the mass of Planet Z? 4. An exoplanet has 216 times the mass of Earth, but has the same density as Earth. What is the gravitational acceleration at the surface of the planet? (use g-9.80 m/s²) 5. A probe orbits an unknown planet while gradually spiraling inward. If the orbital radius is initially 9x10 m and it is moving at 3x10 m/s, how fast is it moving when the orbital radius is 3x10² m?
