Question
in the following questions, assume all objects are moving on trictionless indimes and are on e Obyect A and Object B are moving on the same incine, but O ath uniess otherwise specied ject A Is moving up the ncine and Object B ts moving nown the incine The accelerabkan or obecI A s the acceleration of Object B Object A is an a 30 incline on Earth and Cbject B is on a 3or on the tMoon The acceleration ot object A s the acceleration of Object B Object A ans Object B move on the same incine, bur Object A has twice the mass of Objeci s The acccleration of object A is object B the acceleraion of greater than less than greater than or equal toless than or equal to equal 70 You have a contraption in your room that you REALLY want to destroy. Your room is on the tourth foor of a ten story bualdng You deote to destroy f by throwng n rom your window downwards towards the ground as hard as you can Alter execubng your plan the contraption is not broken at al you need to find a way to make c hit the ground with a larger speed Which of the folowing could you do to achieve your goal? Select al that work Selact one or more a Tie a rock to the cortapton and throw your window b. Throw the contrapton out a wrdow closer to the ground. Drop it rom your wandow dThew the contraption trom a nigher window e. Ask someone with better throwing speed to throw it trom your window Fnish attempl You are logged in as Tenue Log )Explanation / Answer
1. Acceleration of object B is higher in value than object A because when the object moving downward , factor (mg sin theta) added to its motion hence gives somewhat higher value of acceleration than the object moving upward.
2. Acceleration in this case is given by
a= g sin (theta)
If theta is constant I.e 30
Than acceleration of the object purely depends only the value of acceleration due to gravity (g)
As we know the value of g on earth is greater than value of g on moon, so the acceleration of object on earth is greater than on moon for same value of inclination angle
3. Acceleration of the object depends only on the inclination angle and acceleration due to gravity, it is independent of the mass of the object hence the value of acceleration is same for both objects.
