From the information given, there is a 15 kg mass that needs to be accelerated to a velocity of 2.8m/s²
We use the formula: F = m × v.
Where F = force, m = mass and v = velocity.
In our case, m = 15kg and v = 2.8m/s². Therefore:
F = m × v.
F = 15 × 2.8.
F = 42.
Therefore the net force needed to accelerate the 15kg mass to 2.8m/s² is 42 kg m/s² (or 42 Newtons)
Have 5 (or any number) doghouses each with a different insulator. Make sure the other variables are controlled so the experiment if fair. Put a thermometer inside the doghouse and record the temperature inside each doghouse. Whatever doghouse has the highest temperature is the best insulator.
I would say the number of harmonics decrease, because you're adding to the frequency of a wave.
I hope this helps :)
