QUESTION 8 QUESTION 7Acar drives around a 30 degree banked track tradius 10 m) with a constant velocity of 8 m/s Ifit suddenly hits an oil stick, thenthe car slides down the tracko the car slides up the tracko the car neither slides up or down along the tracko mpossible to answer without additional informationQUESTION 8A mass is dropped from rest from a height of 10 meters onto a spring, which then depresses before the mass comes to rest The same apparatus is now brought to Planet X where the acceleration of gravity is4x as large as it is on Earth, and the same mass dropped from the same height onto the same spring Neglecting the size of the spring, which statement is true?The spring compression is the same on Earth as Planet XThe spring compression is half as much on Earth as it is on Planet XO The spring compression is 1/4 as much on Esh as it is on Planet XThe spring compression is 2x as much on Earth as it is on Planet XThe spring compression is 4xas much on Earth as it is on Planet XNOTAQUESTION 9A mass has an initial velocity of 10 m/s, after 5 seconds. the mass has traveled 20 meters. and has a velocity of s m/s You are told that two forces act on the mass dgnore gravity for this problem) if one of theforces has a magnitude of 12 N and acts in the direction that the mass is moving as it decelerates then the work done by the second force isO 100 JO 100 JO 50 JO 50 JO 200 JNeed more information/NOTA

Answer 8: Apply the conservation of energy on the system. Potential energy of the block = Energy stored in the spring mgh=12kx2x=2mghk Here, The compression in the spring is "x" The height of the mass that the falls is "h"Calculate the compression in spring on planet X. x'=2mghk =2m4ghk =22mghk x'=2x Hence, the spring is 2x much compression on the planet X.
