SUMMARY
The speed of a particle moving in the xy plane, defined by the velocity vector v = (6.0t - 4.0t²) i + 6.0 j, equals 10 m/s at t = 2 seconds. The calculation involves determining the magnitude of the velocity vector, which is derived from the components of the vector. The correct approach requires using the formula for speed, which is the square root of the sum of the squares of the velocity components.
