Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.

Part A = The integral with respect to time of a force applied to an object is a measure called impulse, and the impulse applied to an object during a time interval determines its change in momentum during the time interval. The safety of a t-shirt launcher, used to help get crowds cheering at baseball games, is being evaluated. As a first step in the evaluation, engineers consider the design momentum of the launched t-shirts. The springs in the launcher are designed to apply a variable force to a t-shirt over a time interval of t 0.5 s. The force as a function of time is given by F(t) = at² + b, where a = −28 N/s² and b = 7.0 N. The momentum of the t-shirt will be its initial momentum (po = 0) plus its change in momentum due to the applied impulse: pf = po+ St-F(t) dt. By applying the given time dependent function for F(t) and performing the integration, which of the following is the correct expression for pf? ▸ View Available Hint(s) rt=tL 0+(1/3+ ³ + b) 10/20 tL Pf= ○ tL 0+ (13) 기함 a…
