Question
A boxsits at the top of an unloading ramp. As the ramp isgradually tilted down from the horizontal, the box will eventuallystart to slide down the ramp; the ramp then stops further tiltingand is held at an angle. Considering friction realistically,once the box starts to slide, it is most- likely to then: a) Cometo rest in a short distance due to the difference betweenstatic and kinetic friction coefficients. b) Continue to slide at aconstant speed because of friction, and the ramp tilt has stoppedincreasing c) continue to slide at a speed increasing with constantacceleration d) continue to slide with increasingacceleration. 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 Second Law. A boxsits at the top of an unloading ramp.

When block starts to slide then it slides with resultantacceleration. As there is acceleration there would be increase invelocity. The acceleration will be constant through then. This is the illustration of Newtons third law. Hence we get by it.Related Questions
