Explanation:

• For the wheelbarrow: A person applies a push force to overcome inertia and make it move.
• For the vehicle: Friction (from brakes, road - tire interaction) acts to stop the vehicle.
• For the ball rolling down the hill: Gravity pulls the ball down the slope.
• For the soccer ball: A kick (contact force) is applied to make it move.

Answer:
