SUMMARY
The discussion centers on calculating the final velocity of a 0.60 kg ball rolling North at 4.0 m/s after experiencing a force of 0.18 N East for 10 seconds. The correct approach involves recognizing that the acceleration due to the force is perpendicular to the initial velocity. The acceleration is calculated as 0.30 m/s², leading to a final velocity of 12 m/s. However, the Northward component remains unchanged, and the Eastward component must be calculated separately to determine the resultant velocity vector.
