7. A plane has an airspeed of 142 m/s. A 30.0 m/s wind is blowing southward at the same time as the plane is flying. What must be the heading of the plane in order to move directly eastward relative to the ground? A) 78.1° north of east B) 11.9° north of east C) 77.8° north of east D) 12.2° north of east E) 55.3° north of east Required steps: Diagram and Vector components Correct Algebraical solutions Correct numerical solution

Last edit was seconds ago 11 + BIUA EEEE 13 E 2 3 A car mass equal to 1000kg drives on a bridge over a river at a speed of 8m/s. The bridge is 12meters on the greatest. a) what is the total energy of the car while it is on the bridge? b) now imagine the car is parked on a very tall building, how big would the building need to be for the car to have the same total energy that it did in part a? C

Scene 6 conquering device. The final note was left on the stall of a NASA restroom. The final text Kennedy Space Center NASA was rocked when the entire facility was hit with a bioweapon. Calcuu Paraboloid used Florida, USA -- CO opportunity to steal a space shuttle Presumably, this is the final piece of nis wO message followed. Derore you know it, the Mathemagicians are finally going to conquer the world! For my last puzzie, Mars Rover baseball toss problem! (Vertical Motion Equations: The height H of an object t seconds after it is propelled upward with an Intial velocity v represented by H = -% gt2 + vt + h, where g is the gravitational pull and h is the initial height.) Suppose a NASA rover on Mars throws a baseball upward with an initial velocity of 10 meters per second, letting go of the ball 2 meters above the ground. Since the gravity stuff works different on Mars, it will take longer for the bal to land, How much longer will the ball stay in the air on Mars? The answer to this…
