A25 kg cart is moving at 2.0 m/s when a 5.0 n force is applied in the direction it is moving for a distance of 6.0 m. what is the kinetic energy of the cart at the end of the 5.0 m?

The initial kinetic energy of the cart is:

where m is the mass of the cart and v its initial speed.

Then, the force F is applied, in the direction of motion of the cart.The work done by this force is:


For the work-energy theorem, the work done by the force is equal to the variation of kinetic energy of the cart:

And so, the final kinetic energy of the cart is

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
