Kevin completes his morning workout at the pool. he swims 4.00 × 10 3 m (80 laps in the 50.0-m-long pool) in 1.00 h. (a) what is the average velocity of kevin during his workout? (b) what is his average speed? (c) with a burst of speed, kevin swims one 25.0-m stretch in 9.27 s. what is kevin’s average speed over those 25 m?

Which is not one of the major climate zones? question 3 options: rain forest polar tropical temperate

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
