A 238U nucleus is moving in the x direction at 5.0×105 m/s when it decays into an alpha particle (4He) and a 234Th nucleus.

Suppose that, while lying on a beach near the equator watching the Sun set over a calm ocean, you start a stopwatch just as the top of the Sun disappears. You then stand, elevating your eyes by a height H = 1.70 m, and stop the watch when the top of the Sun again disappears. If the elapsed time is t = 11.1 s, what is the radius r of Earth?
The weight of bodies may change somewhat from onelocation to another as a result of the variation of the gravitationalacceleration g with elevation. Accounting for this variationusing the relation, determine the weight ofan 80‑kg person at sea level (z = 0), in Denver (z = 1610 m),and on the top of Mount Everest (z = 8848 m).
A space vehicle is coasting at a constant velocity of 17.1m/s in the +y direction relative to a space station. The pilot of the vehicle fires a RCS (reaction control system) thruster, which causes it to accelerate at 0.324m/s^2 in the +x direction. After 35.1s, the pilot shuts off the RCS thruster. After the RCS thruster is turned off, find the magnitude and the direction of the vehicle's velocity relative to the space station. Express the direction as an angle (in degrees) measured from the +y direction.
The “Screaming Swing” is a carnival ride that is—not surprisingly—a giant swing. It’s actually two swings moving in opposite directions. At the bottom of its arc, a rider in one swing is moving at 30 m/s with respect to the ground in a 50-m-diameter circle. The rider in the other swing is moving in a similarcircle at the same speed, but in the exact opposite direction.a. What is the acceleration, in m/s2 and in units of g, that riders experience?b. At the bottom of the ride, as they pass each other, how fast do the riders move with respect to each other?

(a) The Sun orbits the Milky Way galaxy once each 2.60108 y, with a roughly circular orbit averaging 3.00104 light years in radius. (A light year is the distance traveled by light in 1 y.)

(b) Calculate the average speed of the Sun in its galactic orbit. Does the answer surprise you?
