Chapter 8: Q. 12 (page 550)

Rework Problem 8 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 object can be given asd=-4sin(4t)

Step by step solution

01

Given information

We are givena=4,T=蟺2seconds

02

Find the equation

As the object is moving down the amplitude of the object is a=4

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

in the equation

The angular velocity can be given as

蝇=2蟺T蝇=2蟺蟺2蝇=4

Hence the equation of the object can be given asd=-4sin(4t)

03

Conclusion

The equation of the object can be given asd=-4sin(4t)
