A dog running in an open field has components of velocity vx= 2.8 m/s and vy= -2.3 m/s at time t1= 10.3s . For the time interval from t1= 10.3 to t2= 22.7 , the average acceleration of the dog has magnitude 0.43 m/s2 and direction 33.5 degree measured from the +x-axis toward the +y-axis .
A) At time t2= 22.7s , what are the x- and y-components of the dog's velocity?
B) What is the magnitude of the dog's velocity?
C) What is the direction of the dog's velocity (measured from the +x-axis toward the +y-axis... (answer in θ)

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

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.
