A horizontal projectile is shot with an initial velocity of 28.7 m/s from a height of 6.04 m above the ground. Neglecting air-resistance, what is the direction of the final velocity (in degrees)

How will the system respond to a temperature increase?

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.

What are the north and south poles of a solenoid change with?
