An object of mass 2.7kg is moving in the negative x direction at a velocity of 2.8m/s. it experiences the force shown above for 2.9s. what is the final velocity (in m/s) after the object has experienced the impulse?

Final answer:

The final velocity of the object after experiencing the impulse is -2.57m/s in the negative x direction. This analysis integrates principles of impulse, force, and velocity to deduce the object's post-impulse motion characteristics.

Step-by-step explanation:

In order to determine the final velocity of the object after experiencing a force for 2.9 seconds, the equation Final Velocity = Initial Velocity + (Impulse / Mass) is applied, with Impulse calculated as Force multiplied by Time.

Given the force as -5N and the time as 2.9 seconds, the impulse is computed as -14.5 Ns.

With an initial velocity of 2.8 m/s and a mass of 2.7 kg, the final velocity is found by subtracting the impulse divided by the mass.

This yields a final velocity of -2.57 m/s in the negative x direction.

The negative sign indicates a reversal in the direction from the initial velocity.

Therefore, after undergoing the specified impulse, the object concludes its motion with a velocity of -2.57 m/s along the negative x-axis.

This analysis integrates principles of impulse, force, and velocity to deduce the object's post-impulse motion characteristics.
