Tarzan, who weighs 688 n, swings from a cliff at the end of a vine 18 m long (fig. 8-38). from the top of the cliff to the bottom of the swing, he descends by 3.2 m. the vine will break if the force on it exceeds 950 n. (a) does the vine break? (b) if no, what is the greatest force on it during the swing?

Part a)

here greatest tension is less than the maximum possible tension so it will not break

Part b)

So the greatest tension in the string is given as

Explanation:

Part a)

When Tarzen reached to the bottom of the path then the force on the vine is maximum

so at that position we can write the force equation as

now we can fine the speed of Tarzen by energy conservation

so we will have

Now the tension force in the vine at this position is given as

Now plug in all values in it

So here this is less than the maximum possible tension so it will not break

Part b)

So the greatest tension in the string is given as

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
