- A sailboat moving in the direction shown is tacking to windward against a north wind. The log registers a hull speed of 6.7 knots. A "telltale" (light string tied to the rigging) indicates that the direction of the apparent wind is 33° from the centerline of the boat. What is the true wind velocity vw? 6.7 knots 430 330 Vw knots Answer: vw = iA jet airliner moving at 618 mph due east moves into a region where the wind is blowing at 116 mph in a direction 38° north of west. What is the new velocity of the aircraft?(a) An airplane is flying in a jet stream that is blowing at 45.0 m/s in a direction 23° south of east. Its direction of motion relative to the earth is 45° south of west, while its direction of travel relative to the air is 5° south of west. What is the airplane's speed relative to the air mass? m/s (b) What is the airplane's speed relative to the earth? m/s Additional Materials M Reading
- Recall that the Range equation gives the horizontal distance a projectile can be launched. Suppose there is a slight breeze so that the range equation is modified in the following way: R(0) : = sin(20) – 0.900 R Part A Use Calculus to determine the angle (in degrees) at which the projectile will reach its maximum range. ? OmazA jet airliner moving at 474 mph due east moves into a region where the wind is blowing at 326 mph in a direction 460 north of west. What is the new velocity of the aircraft?Please show your solution on a paper
- How would I Find the magnitude of the sum of the three vectors shown in the figure?A ship is headed due north at a constant 14 miles per hour. Because of the ocean current, the true course of the ship is 15°. If the currents are a constant 12 miles per hour, in what direction are the currents running? ??? °A plane has an airspeed of 200 miles per hour and a heading of 30.0°. The ground speed of the plane is 214 miles per hour, and its true course is in the direction of 32.0°. Find the speed and direction of the air currents, assuming they are constants. mi/hr at ° from due north
- The driver of a motorboat that can move at 12 m/s in still water wishes to travel directly across a narrow strait in which the current flows at 8 m/s. At what angle upstream should the driver head the boat? a) 63.3° b) 27.8° c) 48.1° d) 41.8°For this problem think about a long jumper who takes off and lands from different heights. This is due to the Center of Gravity being higher when they leave the ground then when they contact the sand. If the jumper has a horizontal distance traveled of 7.5 meters and an initial horizontal velocity 6.1 m/s and a takeoff angle of 30 degrees. How far did the jumper fall vertically from takeoff to landing?For the vectors shown in the figure, find the magnitude and direction of BxA
