An object of mass 10.0 kg is initially at rest. A 100 N force causes it to move horizontally through a distance of 6.00 m. What is the change in the kinetic energy of this object?
Ignoring friction, work in is force*distance, and that should equal the change in KE.
i need the answe
To find the change in kinetic energy of an object, we need to know its initial and final kinetic energies.
The initial kinetic energy of the object is zero because it is at rest.
The final kinetic energy can be calculated using the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy. The work done can be calculated by multiplying the force applied to the object by the distance it moves:
Work = Force x Distance
In this case, the force applied is 100 N and the distance moved is 6.00 m, so:
Work = 100 N x 6.00 m = 600 J (Joules)
Since the work done on the object is equal to the change in its kinetic energy, the final kinetic energy is also 600 J.
Now we can find the change in kinetic energy by subtracting the initial kinetic energy from the final kinetic energy:
Change in Kinetic Energy = Final Kinetic Energy - Initial Kinetic Energy
So, Change in Kinetic Energy = 600 J - 0 J = 600 J
Therefore, the change in kinetic energy of the object is 600 Joules.
