Answer:
The average velocity over the given interval = 4.13 m/s
Step-by-step explanation:
The initial velocity, v₀ = 350 m/s [55 degrees W of N]
The final velocity, vf = 150 m/s [30 degrees S of E]
Resolve the initial velcity to the x direction
Resolve the initial velocity to the y direction
Resolve the final velocity to the x-direction
Resolve the final velocity to the y-direction
The acceleration in the x-direction
The acceleration in the y-direction
Find the resultant acceleration
The average velocity over the given interval = 4.13 m/s
