An object with a mass of 6 kg is moving at a speed of 3 m/s. If the object's speed decreases to 1 m/s, what is the work done on the object?
To solve this problem, we can use the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy.
Calculate the initial kinetic energy
The initial velocity of the object is , and the mass is .
The initial kinetic energy () is:
Calculate the final kinetic energy
