An object with a mass of 200 g rests on a coiled spring with a spring constant of k=500 N/m. The spring is compressed by 5 cm.
a. What is the energy stored in the spring? b. How much energy would the spring give to the object?
c. How high will the object reach?​

How are positive ions different from neutral atoms

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?

A10n falling encounters 10n of air resistance (upward force). the net force on the object is:
