Ответ:
position of the peg is given by the equation
now the rate of change in position is given as
given that
now we have
so its speed will be 3.76 m/s in magnitude
Ответ:
First of all, looks like your teacher is indeed pretty horrible. Secondly, the constraints to consider would be proper weight distribution, methods to minimize excessive motion of the building structure, and quantities such as volume and density, which would help in determining the optimal structure. Keeping the frequency of oscillation for a building low in case of an earthquake or natural disaster would also be a priority.
