What is the acceleration of a 17.1 N object that experiences a net tension force of 66.8 N? (acceleration due to gravity is 9.81 m/s/s)

Astring that is fixed at both ends has a length of 1.05 m. when the string vibrates at a frequency of 91.0 hz, a standing wave with five loops is formed. (a) what is the wavelength of the waves that travel on the string? (b) what is the speed of the waves? (c) what is the fundamental frequency of the string?

What properties of a moving object are used in determining the object's energy of motion
