Kinetic energy and Potential energy

[omni]

Vehicle with a weight 2.8 ton Slowing from 100 km/h to 50Kkm/h how much energy can was generate from this Slowing.
(if we Ignore form Friction )
and to which Height this energy was can Climb up the Vehicle Up the hill

thanks.

Consider the equation for kinetic energy. If the velocity is reduced, the kinetic energy is reduced. This energy must go somewhere. Assume it is stored. Now think about the formula for gravitational potential energy. Could this stored energy be transferred to increasing the elevation of the car? Can you derive an equation of the increase in elevation of the car as a function of the initial and final velocities?

Do you know the equation for the Total Energy of an object in terms of its Kinetic Energy and Potential Energy? That's the equation that you use to figure out this question.

yes thanks to both of you i solve it. :)
