Homework Help: Help With Spring Constants and Oscillaions

  1. Dec 15, 2008 #1
    1. The problem statement, all variables and given/known data

    A toy car with mass 0.02 kg is propelled by a spring with a spring constant 80 N/m onto a track. The track. The track contains a loop of radius 0.10m. Ignore any losses dueto friction and use g=10m/s. What is the minimum compression of the spring necessary for the car to complete the loop without leaving the track?

    2. Relevant equations
    ω=√k/m x=mg/k T=2π/ω Vt = rω

    3. The attempt at a solution
