Consider a pitot static tube mounted on the nose of an experimental airplane. a pitot tube measures the total pressure at the tip of the probe (hence sometimes called the pitot pressure), and a pitot static tube combines this with a simultaneous measurement of the free-stream static pressure. the pitot and free-stream static measurements are given below for three different flight conditions. calculate the free-stream mach number at which the airplane is flying for each of the three different conditions1. pitot pressure=1.22×105n/m2 , static pressure=1.01 × 105n/m2 .2. pitot pressure=7222lb/f t2 , static pressure=2116lb/f t2 .3. pitot pressure=13197lb/f t2 , static pressure=1020lb/f t2 .

1.in one challenge on the titan games, competitors have to lift 200 pounds up a long ramp. angel is able to move the weight in 42 seconds. anthony gets it done in only 38 seconds. which statement is true? angel has more power than anthony. angel does more work than anthony. anthony does more work than angel. anthony has more power than angel. 2.a mountain climber exerts 41,000 j of work to climb a cliff. how much power does the climber need if she wants to finish in only 500 seconds? power = work / time 20,500,000 watts 82 watts 0.0122 watts 41,500 watts 3.your family is moving to a new apartment. while lifting a box 83 joules of work is done to put the box on a truck, you exert an upward force of 75 n for 3 s. how much power is required to do this? (hint: you only need two of the 3 numbers given! ) power = work / time 249 watts 25 watts 2075 watts 27.7 watts

Two forces produce equal torques on a door about the door hinge. the first force is applied at the midpoint of the door; the second force is applied at the doorknob. both forces are applied perpendicular to the door. which force has a greater magnitude?
