Answer:
34.45m
Explanation:
Magnitude of a vector is equal to the square root of sum of squares of x & y vectors.
Magnitude =
=
=34.45m
1080000
300 x 60s=18000m/minute
18000 x 60min=1080000m/h
That's false. Displacement would be (r2 - r1) .
Unlike acceleration and velocity, speed does not need to specify the direction of motion. Speed is a scalar quality.
-2m/s
