Answer:
The compression is 
.
Explanation:
A Hooke's law spring compressed has a potential energy
where k is the spring constant and 
the distance to the equilibrium position.
A mass m moving at speed v has a kinetic energy
.
So, in the first part of the problem, the spring is compressed a distance d, and then launch the mass at velocity 
. Knowing that the energy is constant.
If we want to double the kinetic energy, then, the knew kinetic energy for a obtained by compressing the spring a distance D, implies:
But, in the left side we can use the previous equation to obtain:
And this is the compression we are looking for
Explanation:
Physical quantities are usually designated as either vector or scalar quantities.
There are several fundamental quantities know out there that makes definition of the world possible. Derived quantities are obtained from these fundamental quantities.
- A vector quantity expresses a quantity that shows both magnitude and direction.
- With a vector, you know the amount or quantity of measurement taken and the directional attribute.
- A scalar quantity is a quantity that shows magnitude but no direction.
- For example velocity is a vector and speed is a scalar. If a body moves at 10m/s due east, that is a vector.
