Question

For this time interval, find the r component of the plane's average acceleration Constants a 3.22x10 km/h2 At an air show, a jet plane has velocity components Uz = 665 km/h and u,-515 km/h at time 4.45 s and uz = 908 km/h and Uy-365 km/h at time 7.17 s s Answers Answer Requested Part B For this time interval, find the y component of the plane's average acceleration. y15.31 km/h2 Submit PreviousA Answer X Incorrect; Try Again; 4 attempts remaining Part C For this time interval, find the magnitude of its average acceleration

Explanation / Answer

Solution:

B) acceleration = change in velocity / change in time

=> ay = ((365 - 515) / (7.17 - 4.45)) x 60 x 60

=> ay = -198529.41 km/h^2

=> ay = - 2 x 10^5 km /h^2 (approx) ( exact answer is right above)

C) Avg acceleration = sqr root( ax^2 + ay^2) (substituting the approximate values)

=> a = 3.8 x 10^5 km/h^2 (approx).
