A 6.5kg instrument hangs from a wire inside a spaceshuttle which is accelerating upwards from rest at the earth surface. The ship reaches 276m altitude in 15.0s with constant a. Find the force the wire exerts on the instrument.

The  force exerted on the instrument is  

Explanation:

From the question we are told  that  

          The mass of the instrument  is  

          The height attained is  

           The  time  taken is  

Now  applying equation of motion we have that

Now  the space shuttle is  accelerating from rest thus  u= 0m/s

   So  

Now  looking at the question we can deduce that  the weight of the instrument is  downward and the reaction force of the wire(N) is  upward

So this can be mathematically be represented as

Thus  

substituting values  

what question you dont ask a question

explanation:

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
