- A treasure map directs you to start at a palm tree and walk due north for 15.0 m. You are then to turn 90∘ and walk 22.0 m; then turn 90∘ again and walk 5.00 m. Give the distance from the palm tree, and the direction relative to north, for each of the four possible locations of the treasure.Can't understand how to get vector r. a=1.43, b=0.915, the total trip required was 1.582 hours, and c =4.60 at 72.8 degree angle. Do I do the pythagorean theorem?On the map, let the +x-axis point east and the +y-axis north. An airplane flies at 880 km/h northwestward direction (i.e., midway between north and west). Find the components of its velocity. Enter the x and y components of the velocity separated by a comma. I understand the quadrant, and origin but not how to then figure components of airplane's velocity. Can you simply get me up to the speed?
- Please help with the solution to this problem using (km/s). I know we will use Hohmann Transfer and a combined plane change. In the opening scene of the movie “Gravity” Dr Ryan Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) are required to transit from the Hubble Space Telescope (Altitude 600 km, 28.5 degree inclination) to the International Space Station (Altitude 400 km, 51.6 degree inclination) using nothing but their Manned Maneuvering Units (MMU). An MMU has a delta V capability of about 30 m/s, and it would be impossible to perform this maneuver with so little delta V, but… a.) How much delta V would be required for this maneuver? b.) What if the maneuver did not require an inclination change (altitude change only?)A long distance commercial passenger plane flies North at 910 km/h. At the same time, there is wind of 30 km/h from the West. Use a scaled diagram, Pythagorean Theorem and trigonometry to answer the following . a) What is the magnitude of the resultant velocity? b) What is the direction of the resultant ( North, South, East, West, NE, NW, SE or SW). c). What is the angle of the resultant relative to due East? Round your answer to the nearest tenth.Mr. M is walking to Mr. T’s house. He take the shortcut across an open field. His first displacement is 140 m[E35N]. He then walks 200.0m[E]. What is Mr. M’s total displacement?
