- A person is traveling in a plane at 400 miles/hour due east with a strong crosswind blowing from north to south at 200 miles/hour. A) What is the velocity and direction angle of the plane in the crosswind? B) What is the total distance traveled by the airplane in one hour?A plane flying at 78.2 m/s [W32°S] takes 42 seconds to change its velocity to 78.2 m/s [S32°E]. a) Solve for the change in velocity of the plane algebraically, resolving vectors into their x- and y-components. b) What was the average acceleration of the plane over this time interval? c) Explain why the speed of the plane didn't change and yet the plane underwent acceleration. Please label sketches with events as well as GRASS and explanations to show your work. Please label triangle sides. Remember to have the magnitude rounded to a reasonable number of sig figs, the unit and the direction (if needed) in your answers.Stuck need help!

Given: Three forces act on particle P. Force A has a magnitude of 15 N and acts 60° CCW from the positive x-axis. Force B has a magnitude of 60 N and acts along a ray from point P with a slope of -4/3. Force C has a magnitude of 10 N and acts straight left (180° CCW from positive x- axis). Find the Vector Sum: a. Draw a neat, labeled, scaled diagram representing the tip-to-tail vector addition R=A+B+C. Rx = 15cos60+60(3/5) — 10 and Ry = 15sin60-60(4/5) b. Add the three vectors to find the scalar components of the resultant, Rx and Ry. C. Find the magnitude of the resultant R and the angle 0 it makes with the positive x-axis.
