After hitting it across the ice with a hockey stick, a 0.2kg hockey puck increases its speed from 0 to 10m/s. If the average force that the stick exerts on the puck is 200 N, what is the distance that the force is exerted over?

How do you tell if someone actually cares about you? and just say they do?

What sort of waves exhibit the doppler effect?

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.
