An astronaut, whose mission is to go where no one has gone before, lands on a spherical planet in a distant galaxy. As she stands on the surface of the planet, she releases a small rock from rest and finds that it takes the rock 0.460 s to fall 1.90 m. Part A If the radius of the planet is 8.90×107 m, what is the mass of the planet? Express your answer with the appropriate units. mp =

You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 4600 m/s. By observing the planet, you determine its radius to be 4.48×106 m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 14.6 m/s at an angle of 30.8∘ above the horizontal. Part A If resistance due to the planet's atmosphere is negligible, what is the horizontal range of the projectile? Express your answer with the appropriate units. d =

A thin, light wire is wrapped around the rim of a wheel, as shown in (Figure 1). The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.276 m. An object of mass 4.10 kg is suspended from the free end of the wire. The system is released from rest and the suspended object descends with constant acceleration.
