physics ooo Verizon 8:14 AM 0 99% livetext.com PHYS 221 SECTION 01 FALL 2015-WRITING ASSIGNMENT #1 ID A wildlife biologist is studying the hunting patlerms of jaguars. She has attachodl a GPS collar to an animal to track its movements. The collar transmits data on the jaguar's position and velocity. The graph below shows the jaguar's velocity as a fiunction of time as the animal moves along a straight path in the rain forest In your writing assignment, describe ae words, are explaining to a friend who has never taken a physics cowrse, the motion ofhejguar oner the period of ime shown in the grapih righ Time." H -, left Here are some questions you might consider answering in your writlen description Is the he jaguar always moving or is she somctimes Does she always travel in the same direction? If not, when does she change direction? Does the jaguar ever accelerne? Decelerane Where is her acceleration grealest in magnitude? When is her speed greatest in magnitude? When is the jaguar furthest away from her starting point? Does she end up back where she started Your write-up must satisfy the folloaing. It must be submitted electronically (preferably as a Microsoft Word or pdf document) to the Assignments area of the LiveText pages for our coursc Your write-up will be graded 50% on a comod explanation ofthe physics and 5056 onthe quality of the writing .Your write-up should consist of standard English only (no fommulas or mathematical tbe Be clear and concise in your written expression. Your writing will also be judged use of complete sentences with correct grammar and punctuation * You may work together in small groups to discuss the physics of the velocity-time graph but your write-up must be in your own words (no team-writing efforts If you work together in a small groop to discuss the plysics, you matt the names of all those who participated in the group discussions * st on Dr. J.G. tacyExplanation / Answer
-the jaguar is moving moving as its velocity is constantly changing ,but it is motionless at point E and H where its velocity is zero
- no, it travels in different direction , from A to E it travels in one direction and then from E to H it travels in opposite direction
-yes , the slope of the velocity time curve is the accelerarion. the positve slope represents acceleration and negative slope represents deacceleration.
- the slope from A to B is greatest and hence it is the greatest deacceleration . if we consider de acceleration then D to e is the greatest de acceleration.
- greatest magnitude of acceleration is actually deacceleration from D to E where the slope is maximum
- the greatest speed is at Point C .
-as the jaguar first goes in one direction and then reverses her direction,
the maximum displacement will be at E , as the velocity is still positive , it would have covered the maximum distance in that direction, before reveresing
-no, she does not end up at the starting point. this is because the area under the curve represents the displacement,now, we can see the area under the positive side is much more than the negative side. hence the dispacement is positve. if the net displacement was zero then the jaguar would have ended up at the starting point.
