1. A person standing on Earth drops a ball. At the same time, a person standing at the bottom of a spaceship accelerating at 9.8m/s^2. In the absence of any significant field in deep space, drops a ball. What would these people observe 2. Research general relativity and problems with the theory. Identify two possible solutions to problems with general relativity and the behaviour of galaxies. Do the solutions seem plausible to you? Why or why not?

Imagine you are the orbital engineer for the first NASA space shot to Ceres, the largest known asteroid. Ceres’s nearly circular orbit around the sun has a radius of R = 2.77 AU. After being launched from the earth, the probe will initially be in a circular orbit around the sun with the same radius (r_{c} = 1.0 AU) and the same orbital speed (|\vec{v}_{c}| = 6.28 AU/y) as the earth’s orbit. The probe’s rocket engines will then fire briefly...

An astronaut on a rock trying to land on a planet his ship was damaged. Although the astronaut does not know the gravitational accelerationIt has a good field of view to measure and measures the height of the rocktakes two measurements to measure. In the first measurement, taking a piece of boulder,released from the edge of the rock to the ground in 4 s.measures the fall. In the second, up another rock from the same pointthrows correctly. That the piece...

An astronaut is exploring an unknown planet when she accidentally drops an oxygen canister into a 1.90-m-deep pool filled with an unknown liquid. Although she dropped the canister 46 cm from the edge, it appears to be 56 cm away when she peers in from the edge. What is the liquid's index of refraction? Assume that the planet's atmosphere is similar to earth's.

A man drops a rock into a well. (a) The man hears the sound of the splash 2.20 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (answer in meters) (b) If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated? (percentage)
