Math and the study of motion
Answer:
Or
with
Explanation:
We know that the initial speed is:
1350 m/s at a 25 degree angle
And the final position after 10.20 sec is:
23,500 m away in a 55 degree direction
In this problem we have:
Final position in x:
Where is the initial velocity in x
So:
We solve for
X component of velocity
Where is the acceleration in the direction x
And
Therefore:
Final position in y:
Where is the initial velocity in y
So:
We solve for
Y component of velocity
Where is the acceleration in the direction y
And
Therefore:
Note then that the final velocity V is a two component vector
The magnitude of the final speed is:
And the angle that forms with the x axis is:
