Let's analyze the velocity-time graphs provided to determine the forces acting on the object.

1. Horizontal Velocity Component (vx):

   • The graph for $v_x$ shows a constant velocity over time, meaning there is no change in the horizontal velocity component.
   • Since acceleration is the rate of change of velocity, and $v_x$ is constant, the horizontal acceleration $a_x$ is zero.
   • Therefore, there is no net horizontal force acting on the object because $F_x = m \cdot a_x = 0$.

2. Vertical Velocity Component (vy):

   • The graph for $v_y$ shows a linearly decreasing velocity over time, which indicates a constant negative acceleration in the vertical direction.
   • Since the vertical velocity is decreasing, there is a downward force causing this deceleration.
   • Thus, there is a constant downward force acting on the object, which could represent gravitational or other downward force effects.

Conclusion:

Forces acting on the object:

• No horizontal force (as $v_x$ is constant).
• A constant downward force (as $v_y$ is decreasing).

This setup suggests that the object might be in free fall or influenced by gravity alone in the vertical direction while moving with a constant horizontal velocity.

Tip:

Remember, a constant slope on a velocity-time graph implies constant acceleration, while a flat line implies zero acceleration.
