How do you find mean kinetic energy when given only mass and horizontal distance traveled?

You don't have enough information in this case. Kinetic energy depends on mass and speed. Speed can be calculated as distance / time - and no time is given, nor is there any other information that allows you to calculate the time.
Note that even if time is given, you can calculate the average (mean) speed, but that will only give you a rough idea of the mean kinetic energy. In this problem, if the speed changes a lot, the average kinetic energy (averaged over time) will be greater than in the case of a constant speed. This is because kinetic energy is proportional to the square of the speed.

A particle is projected at 60 degree to the horizontal with a kinetic energy k the kinetic energy at highest point is?
k/4
What energy or momentum of a vehicle can be offset by allwoing an increase in stopping distance?
kinetic
How do you find force while given kinetic energy and distance?
The work (energy) done on an object is Force x Distance. If there is no friction, and the object started at rest, then this will also be the kinetic energy that the object has. Then the kinetic energy, Ek = F * d, so F = Ek / d
How the hell do you measure motion?
You can measure distance traveled, energy used or work done.
Is an increase in kinetic energy directly proportional to the time it takes for an object to fall slash distance it falls?
The kinetic energy of a falling object is directly proportional to the distance it falls.But the distance is not directly proportional to the time in fall, so the KE is not directly proportionalto the time either.
What is the distance between kinetic and potential energy?
Kinetic and potential energy are a type of energy, not a measurement of distance.

If you double the speed of a car you increase its force of impact by how many times?
four times as great
The kinetic or potential energy associated with the motion and position of an object is?
This is actually two questions. Energy relating to the motion of an object is kinetic energy. Energy related to its position is potential energy (as with a brick suspended at some distance above the ground). Release the brick and its potential energy is converted to kinetic energy. The two are complementary. As the brick accelerates toward the ground its kinetic energy increases; as the distance decreases during that acceleration, it's potential energy decreases.
How does kinetic energy is delivered to you?
By any source of electrical power moving any object any amount of distance. Because kinetic energy is the ability to move something with a force. So without kinetic energy it would be stored energy called potential energy.
What 2 factors do you need to know to determine the speed of an object?
you have to look at a given distances that it covered when it moved , and at the time it took to cover that distance
If a force of 600N had acted over the same distance what would have been the gain in kinetic energy?
Work = Force * Distance Work = Change in Kinetic Energy Symbolically: W = Fd = ΔK Now, since the change in kinetic energy is an interval, then: ΔK = (K_final) - (K_initial) This difference indicates the gain or loss. As such, merely multiply 600N by the distance it travels through.

Why would the final kinetic energy before impact be less the initial potential energy of an object dropped from a kilometer height?
It is easiest to think of initial potential energy as the "distance" the object is able to fall. If it has not fallen the distance yet, then of course kinetic energy would be less.
