SUMMARY
The problem involves calculating the force required to push a 22kg bobsled down a 6-degree incline with a coefficient of kinetic friction of 0.10, aiming for a speed of 60 km/h over a distance of 75 meters. The acceleration needed to achieve this speed is determined to be 1.85 m/s², leading to a required force of 40.7 N. The frictional force opposing the motion is calculated as 21 N. The final answer aligns with the solution provided in the textbook.
