Step-by-step explanation:
Given:
The magnitude, v=12
The angle it makes with the positive x-axis =
Now for a vector (x,y)
; and
Therefore:
Similarly:
Recall that:
Therefore:
The vector in the form ai+bj is therefore:
Answer:
B
Step-by-step explanation:
This is a distance-rate-time problem, so we need to use the equation: , where d is the distance, r is the rate, and t is the time.
Here, we know that the total distance is 150, so d = 150. Also, we are given that Sergio's rate is 60 mph, so r = 60. Put these in:
d = rt
150 = 60t
To solve for t, we divide both sides by 60. Because we are dividing and not multiplying, we know that B is the only one that is incorrect.
Hope this helps!
