Homework Help: How do I calculate the Velocity when only given the force and weight?

  1. Jul 15, 2013 #1
    I do not know how to calculate the velocity of a 50.0g steel ball shot from a slingshot with a 120N/m spring constant when pulled back 35cm and released.

    Can someone help me with the formulas to use?

    As this looks like homework, I moved the thread to the homework section.

    Did you try energy conservation?

    The elastic potential energy is given by [itex]PE=\frac{1}{2}kx^2[/itex]

    The potential energy will be converted to kinetic energy given by [itex]KE=\frac{1}{2}mv^2[/itex]
