Yoou are in the middle of a large field facing 330 degrees. you run at 5.0 m/sec for 23 seconds. then you turn to face a direction of 125 degrees and run at 6.0 m/sec for 15 seconds. what is your final displacement?

Why don't you see your reflection in water with waves or repples

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

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.
