Problem 5E

A jet plane is flying at a constant altitude. At time t1 = 0, it has components of velocity vx = 90 m/s, vy = 110 m/s. At time t2 = 30.0 s, the components are vx = - 170 m/s, vy = 40 m/s. (a) Sketch the velocity vectors at t1 and t2. How do these two vectors differ? For this time interval calculate (b) the components of the average acceleration, and (c) the magnitude and direction of the average acceleration.

For this time interval calculate (b) the components of the average acceleration, and (c) the magnitude and direction of the average acceleration.

ANSWER:

Solution 5E
Step 1 :

In this question, we need to

Sketch velocity vectors for time t1 and t2

And find the difference between these two vectors

Find the components of average acceleration of jet plane

Find the magnitude and direction of the average acceleration

Considering the data given

We have

Velocity along x-component at time t1=0s

Velocity along y-component at time t1=0s

Velocity along x-component at time t2=30s

Velocity along y-component at time 2t=30s
