Understanding the Concepts
* Acceleration: A change in velocity (speeding up or slowing down).
* Net Force: The overall force acting on an object, considering all forces acting on it.
* Constant Velocity: Moving at a steady speed in a straight line.
The Key: For an object to move at constant velocity, the net force acting on it must be zero.
Applying the Concepts
1. The Car is Accelerating: Since the car has a net force of 3674 N, it is accelerating downhill.
2. To Stop Acceleration: To achieve constant velocity, we need to counter the existing 3674 N force.
3. Equal and Opposite Force: This means we need to apply an additional force of 3674 N in the opposite direction (uphill) to cancel out the existing downhill force.
Conclusion:
To make the car move at constant velocity downhill, an additional force of 3674 N directed uphill is required. This force would create a net force of zero, stopping the car from accelerating.
