You didn't give me any values, but I can give you a formula that will answer your question. The force exerted by a spring is given as F = -KX, where K is the spring constant and x is the distance the spring is compressed or stretched. When the spring is compressed fully, it has a force F. When the spring is at equilibrium(aka not stretched), it has a force of zero. We can average these to say that the Average force of a spring is F = 1/2 -KX. We can now substitute the -1/2 KX into the equation F = ma. This yeilds -1/2 KX = ma. Solve for acceleration, we get (-1/2 KX)/m = a. Multiply this quantity by the amount of time the spring pushed on the object, and you have your velocity. Hope this helps whoever asked. --An AP Physics Student Bored in Study Hall

What is the spring constant of a spring?
The ratio of force applied to how much the spring streches (or compresses). In the SI, the spring constant would be expressed in Newtons/meter. A larger spring constant means the spring is "stiffer" - more force is required to stretch it a certain amount.
When a 13.2kg mass is placed on a top of a vertical spring the spring compresses 5.93 cm. find the force constant of the spring.?
2181 N/m
How do you calculate the natural length of a spring with hooke's law?
Hooke's law is not related to any "natural length". Rather, it defines a string constant: how much the string extends or compresses, depending on the applied force. In SI units, the spring constant would be measured in newton/meter.
What does spring loaded bb gun mean?
The Spring is the power source for the gun. When the gun is cocked the spring compresses and when the trigger is pulled the spring releases and pushes a piston that compresses a tube fill of air that fires a BB out of the barrel.
Is the spring constant is constant on the moon?
no the spring constant is not constant on moon because there is no restoring force there
If the force constant of a spring is 25 newtons per meter and it has a mass of 0.45kg with an amplitude of 0.32m what is its maximum velocity?
The spring constant (K) is 25 N/M, Êthe maximum velocity is Êgiven ÊbyÊ AW where ÊA is Êthe amplitude (0.32 m) and w is given by the formula (k/m)^0.5. ÊTherefore the maximum velocity is Ê2.4 m/s (0.32 x (25/0.45)^0.5).
How do you calculate velocity of a box attached to a spring?
some basic physics will tell you that the mass of the box times acceleration due to gravity times the height of the box above the ground, minus the force of the spring or the spring constant times the distance the spring stretches will equal .5 times the mass of the box times the velocity squared mgh-kx=.5mv2
When 100g mass attached to a spring with constant 240Nm oscillates its velocity is 20cms at x equals negative 5cm what is the amplitude?
Please do your homework by yourself.
When a spring compresses does its kinetic energy increase?
No. Its potential energy does decrease.
What is the characteristics of springs with large spring constant in hooke's law?
larger the spring constant of a spring, the more stiffer it is.
If a spring with spring constant k is cut into two equal parts what will be the spring constant of each part?
2k
A 210 g block is pressed against a spring of force constant 1.40 kNm until the block compresses the spring 10.0 cm The spring rests at the bottom of a ramp inclined at 60.0 to the horizontal Use e?
a system shown in figure is released from pulley from rest.pulley and spring is massless and friction is absent everywhere .the speed of 5kg when 2kg block leaves the ground is how much
