1 a 03kg mas is attached to a spring with a spring constant, Ask an Expert

Academics

1. A 0.3kg mas is attached to a spring with a spring constant of 120n/m and resys on a frictionless horizontal surface. It is compressed 17cm and released. Find forces and inital acceleration.

2. A spring is hung from a ceiling, and an object attached to its lower end stretches the spring 3.00cm from its unstretched position. If k=31n/m, what is the mass of the object?
