Chapter 2, Problem 18PQ

(a)

To determine

Sketch for the condition y→=(y0cos2πtT)j^.

(a)

Expert Solution

Answer to Problem 18PQ

The sketch for the condition y→=(y0cos2πtT)j^ is given in figure 1.

Explanation of Solution

Write an expression for the condition.

y→=(y0cos2πtT)j^

Here, y→ is the instantaneous position, y0 is the initial position, t is the time and T is the time period.

Here, y axis points upwards. The time starts at t=0. there will not be any negative value for time. At time t=0 the particle is at +y0.

Thus, the sketch for the condition y→=(y0cos2πtT)j^ is given in figure 1.

(b)

Expert Solution

Answer to Problem 18PQ

The position of the particle at t=0, 12T, T,32T, 2T and 52T are y0j^, −y0j^, y0j^, −y0j^, y0j^ and −y0j^ respectively and the positions are marked in figure 1.

Explanation of Solution

Write an expression for the condition.

y→=(y0cos2πtT)j^ (I)

Conclusion:

For t=0:

Substitute 0 for t in equation (I).to find y→.

y→=(y0cos2π(0)T)j^=(y0cos(0))j^=y0j^

For t=T2:

Substitute T/2 for t in equation (I).to find y→.

y→=(y0cos2π(T2)T)j^=(y0cos(π))j^=−y0j^

For t=T:

Substitute T for t in equation (I).to find y→.

y→=(y0cos2π(T)T)j^=(y0cos(2π))j^=y0j^

For t=3T2:

Substitute 3T/2 for t in equation (I).to find y→.

y→=(y0cos2π(3T2)T)j^=(y0cos(3π))j^=−y0j^

For t=2T:

Substitute 2T for t in equation (I).to find y→.

y→=(y0cos2π(2T)T)j^=(y0cos(4π))j^=y0j^

For t=5T2:

Substitute 5T/2 for t in equation (I).to find y→.

y→=(y0cos2π(5T2)T)j^=(y0cos(5π))j^=−y0j^

Thus, the particle can be seen at y0j^, −y0j^, y0j^, −y0j^, y0j^ and −y0j^ when the time is t=0, 12T, T,32T, 2T and 52T respectively and the positions are marked in figure 1.
