Spring constant- calculating velocity

Click For Summary
SUMMARY

The discussion centers on calculating the launch velocity of a contraption using Hooke's Law and the spring constant. The group measured a launch speed of 15.24 m/s. It was confirmed that while the angle of launch may affect the trajectory, the launch velocity remains constant if the displacement from the equilibrium position is measured accurately. This highlights the relationship between spring constant and energy in elastic materials.

Hello all, for my experiment my group needed to use Hookes spring constant to help us find the energy in the elastics for our contraption we made. We found that the launch speed to be 15.24m/s. I was wondering if this would be changed if we fired at different angle or would the launch velocity always be the same.
Thanks

If you measure the displacement from the equilibrium position, which will be different for different angles, the speed will be the same.
