A rock sample is analyzed using the Carbon 14 method. If the D/P rario is 1/64, how old is the sample in years?

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
