Answer:
t=18s
Explanation:
The final position of an object moving at constant speed is given by the formula , where is its initial position, v its speed and t the time elapsed.
For the cheetah we have , and for the gazelle . We want to know at which t their positions are equal, that is, , which means,
Where we can do:
We then substitute the values we have (the initial position of the cheetah is 0m), writing the meters in km so distance units cancel out correctly:
On the last step we just multiply by 3600 because is the number of seconds in an hour.
Answer:
The magnitude of the velocity is approximately 11.45 units
Explanation:
Since they give us the x and y components of the vector velocity, we can find its magnitude via the Pythagorean theorem:
