At the end of a very long taut string, of mass 0.008 kg, and linear density 0.021 kg / m, a MAS is produced, perpendicular to the direction of the string, of amplitude 0.322 cm and frequency 16 Hz. If this disturbance propagates along the rope with velocity 43m / s, determine: a. the wavelength of the generated waves.

B. The energy that these waves transmit.

C. The power that transmits the waves produced along the string.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
