FOR THIS QUESTION, solve as if you are on the moon and use moon gravity ( g= 1.7 m/s2) The astronauts decide to play basketball on the moon. The ball rolls off the basket at a height of 2.1 meters and lands 4.5 meters from the hoop. How fast was it going as it left the hoop?

A) 28 m/s
B) 0 2.5 m/s
C) 1.8 m/s
D) 1.6 m/s

How many dots must be added to the symbol to properly represent a standard nitrogen ion? a) 1 b) 3 c) 5 d) 8

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.
