Question

At an air show, a jet plane has velocity components vx = 695 km/h and vy = 440 km/h at time 4.85s and vx= 933km/h and vy = 465 km/h at time 7.12 s. For this time interval, find (a) the x and y components of the plane’s average acceleration and (b) the magnitude and direction of its average acceleration

find (a) the x and y components of the plane’s average acceleration and (b) the magnitude and direction of its average acceleration
d) for this time interval, find the direction of its average acceleration?
=? counterclockwise from + x axis

im having a hard time solving this problem

Answer 1

There is nothing hard here.

ax= (Vxf-Vxi)/timedifference
(933-695)/(7.12-4.85) solve that, then do the same for
ay.

b) magnitude: sqrt(ax^2+ay^2)
direction: arctan ay/ax

Answer 2

ax i got 104.8 but its wrong and i rounded it to 105
