First identify the problem: Do you have Torsion Springs or Extension Springs? Torsion Springs are mounted above the garage door opening, while Extension Springs are mounted above the garage door track. Torsion Springs twist while Extension Springs stretch under pressure.
Like Extension Springs, Torsion Springs are usually installed in matched pairs. Single Torsion Spring applications are usually fine with single or one-car garage door applications. After identifying the broken spring(s), now we can move on to measuring.
Measuring your broken or unwound Garage Door Torsion Springs or Extension Springs is simple as 1-2-3! First, you need to measure the length of 20 coils starting at the break of the spring. Measuring at the break of the spring will assure you that your coils are at their tightest point. Make sure to measure to the nearest 1/16th of an inch for accuracy.
Secondly, measure the Inside Diameter of the Garage Door Spring. Torsion Springs come in many different sizes but typically found in 1 3/4" - 2" and 2 1/4" Inside Diameters. Extension Springs are much smaller. Measuring the inside diameter of Extension Springs can be difficult due to small size so measuring the outside diameter is fine. If measuring Extension Springs, you may need to call or email us for further assistance.
Last, measure the length of your Garage Door Spring(s). Torsion Springs and Extension Springs are measured from end to end less end connecting pieces. Basically just measure the spring coils, not the cones on Torsion Springs, or Loops, clips on Extension Springs. Measure to the nearest 1/2" and you'll be fine.

A miniature spring-loaded, radio-controlled gun is mounted on an air puck. The gun's bullet has a mass of 5 g?
A miniature spring-loaded, radio-controlled gun is mounted on an air puck. The gun's bullet has a mass of 5.00 g, and the gun and puck have a combined mass of 120 g. With the system initially at rest, the radio controlled trigger releases the bullet causing the puck and empty gun to move with a speed of 0.500m/s. what is the bullet's speed?
use conservation of momentum
m1 * v1 = m2 * v2
m1 = puck mass
v1 = puck velocity
m2 = bullet mass
v2 = bullet velocity
