Which is traveling faster, a car whose velocity vector is 201 + 25), or a car whose velocity vector is 30i, assuming that the units are the same for both directions? is the faster car. at what speed is the faster car traveling? speed = enter the speed as a number, using exact values or at least 4 decimal place accuracy.

Answer with explanation:

For any object having the velocity vector as

the magnitude of velocity is given by

For car 1 the velocity vector is

Therefore

Similarly for car 2 we have

Therefore

Comparing both the values we find that car 1 has the greater speed.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
