Question

x dirextion =30cos(45)+270

y direction =30 sin(45)

i did sqrt((30cos45+270)^2+(30sin(45))^2)==291.985 rounds to 291.99 right? what am i missing

If it flies in a steady 3 mi /hr wind that blows horizontally toward the southwest (45 south n airplane flies horizontally from east to west at 270 f west), find the speed and direction of the airplane relative to the ground Assume that the vector w gives the direction and speed of the wind, the vector vp gives the direction and speed of the airplane relative the air, and the vector v gives the direction and speed of the airplane relative to the ground. Place the vectors in a coordinate system. Choose the correct diagram below. O A The speed of the airplane is approximately 291.99 mi/hr (Simplify your answer. Do not round until the final answer.

Explanation / Answer

dear student,

you are right with your approach and the answer will be round off to next significant digit , so u have the right answer . as the value after decimal is 0.985 and the second digit is greater than 5 so it is replaced with 0.99 in answer , please have a look on significant digit concepts from physics units measurement chapter and u r done.
