Question
A box sits at the top of anunloading ramp. As the ramp is gradually tilted downfrom the horizontal, the box will eventually start to slide downthe ramp; the ramp then stops further tilting and is held at anangle. Considering friction realistically, once the boxstarts to slide, it is most- likely to then: a) Come to rest in ashort distance due to the difference between static andkinetic friction coefficients. b) Continue to slide at a constantspeed because of friction, and the ramp tilt has stopped increasingc) continue to slide at a speed increasing with constantacceleration d) continue to slide with increasing acceleration. lastly: If you blow up a balloon then release it, the balloonwill fly away as the air rushes out. This is an illustrationof EXPLAIN: a) Newton's first law b) Newton's third lawc) Galileo's Law of Inertia d) Newton's SecondLaw. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! lastly: If you blow up a balloon then release it, the balloonwill fly away as the air rushes out. This is an illustrationof EXPLAIN: a) Newton's first law b) Newton's third lawc) Galileo's Law of Inertia d) Newton's SecondLaw. HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Explanation / Answer
The box will slide with an increasing speed and constantacceleration because once it begins moving it's motion is onlyopposed by kinetic friction which is less than static friction. The balloon is an example of newton's second law, the gas rushingout the hole is creating a force causing the balloon to accelerate.
