A mass of 0.8 kg is fixed at a vertical spring with an unknown spring constant. When spring is released from rest, it extends to 15cm before it stops. As the system oscillates with Simple Harmonic Motion (SHM) the weight is pulled down 20cm further downward and being released. 1. What is the spring constant?
2. What is the total energy of the system?
3. What is the angular frequency of spring?
4. What is the velocity of the system at x=10cm below equilibrium position?

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
