A mass, m1 = 5.5 kg, is in equilibrium while connected to a light spring of constant k = 132 N/m that is fastened to a wall (see a). A second mass, m2 = 10.9 kg, is slowly pushed up against mass m1, compressing the spring by the amount Ai = 0.17 m (see b). The system is then ...

Physics
A toy gun uses a spring to shoot a ball with a mass of 5.0 g. The spring is loaded by compressing it 5.0 cm and has a spring constant of 288 N/m. The end of the spring is at the end of the gun (the ball does not travel any distance inside the gun after the spring) and the ...

Physics-Please check?
Would changing the frequency of a wave cause a change in amplitude? I would say NO because they don't affect each other, correct? If I had a wave diagram will 4 complete waves showing and it said the diagram represented 4 sec in time the frequency would be 1cycle/ per second, ...
