Chapter 8: Q. 9 (page 549)

Rework Problem 5 under the same conditions except that, at time t = 0, the object is at its resting position and moving down.

Short Answer

Expert verified

The equation of the motion isd=-5sin(蟺t)

Step by step solution

01

Given information

We are givena=5,T=2seconds

02

Find the equation

As the object is moving down the amplitude of the object is a=5

Since at t=0 the object is at resting position and moving downward we will use -sinin the equation

The angular velocity can be given as

蝇=2蟺T蝇=2蟺2蝇=2

Hence the equation becomesd=-5sin(蟺t)

03

Conclusion

The equation of the motion becomesd=-5sin(蟺t)
