Question

Consider the sinusoidal relationship for d given in Part B [d=kcos(2?t) for some constant k ] and the sinusoidal relationship for v given in Part C [v=hsin(2?t) for some constant h]

Find the values of d and v at t=1.5s.

Answer 1

To find the values of d and v at t=1.5s, substitute t=1.5s into the given equations for d and v: d=kcos(2?t) and v=hsin(2?t), respectively.

Step-by-step explanation:

To find the values of d and v at t=1.5s, we can substitute the value of t into the equations given for d and v.

For d, the equation is d=kcos(2?t). If we substitute t=1.5s into this equation, we get d=kcos(2?*1.5)=kcos(3?).

For v, the equation is v=hsin(2?t). Substituting t=1.5s, we get v=hsin(2?*1.5)=hsin(3?).

Therefore, at t=1.5s, the values of d and v are d=kcos(3?) and v=hsin(3?).
