Atextbook of mass 2.09 kg rests on a frictionless, horizontal surface. a cord attached to the book passes over a pulley whose diameter is 0.190 m, to a hanging book with mass 3.08 kg. the system is released from rest, and the books are observed to move a distance 1.26 m over a time interval of 0.800 s.

The tension in the part of the cord attached to the textbook is 6.58 N.

Explanation:

Given that,

Mass of textbook = 2.09 kg

Diameter = 0.190 m

Mass of hanging book = 3.08 kg

Distance = 1.26 m

Time interval = 0.800 s

Suppose,we need to calculate the tension in the part of the cord attached to the textbook

We need to calculate the acceleration

Using equation of motion

Put the value into the formula

We need to calculate the tension

When the book is moving with acceleration

Using formula of tension

Hence, The tension in the part of the cord attached to the textbook is 6.58 N.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
