please help me...y is the displacement of an oscillating object from a centralposition at time t. For each problem, find an equation of the fory=A sin Bt or y=A cos Bt that satisfies the given conditions. a) Displacement from the t axis is 0 ft when t is 0, amplitudeis 5 ft, and period is 2 sec. please help me...
y is the displacement of an oscillating object from a centralposition at time t. For each problem, find an equation of the fory=A sin Bt or y=A cos Bt that satisfies the given conditions. a) Displacement from the t axis is 0 ft when t is 0, amplitudeis 5 ft, and period is 2 sec.
Explanation / Answer
A=5 (amplitude) since the amplitude is zero when t=0, the function must be a sinewave. we want the period to be 2, so we have 2=Bt=B*2. soB= our equation is then: y=5sin(t)
