Zola (the wonder dog) is told to sit and stay on a bathroom scale which reads 150 newtons with her on it.


Zola (the wonder dog) is told to sit and stay on a bathroom scale which reads 150 newtons with her on it. But she soon gets bored with sitting on the scale and leaps straight up into the air with an acceleration of magnitude 2 m/s^2.  

a) What is Zola's mass?  

b) What is the reading on the scale as she launches herself upward?

Solutions

Expert Solution

Data:

a)

b)

Solution:

Part a)

The weight is defined as:

Isolating :

replacing values given in DATA:

Part b)

The reading on the scale as she launches herself upward:

Replacing values we have:

Finally, the total reading on the scale including the dog's weight is:

The scale in Beatrice's bathroom gives readings which are normally distributed, with mean equal to the weight of the object placed on it
The scale in Beatrice's bathroom gives readings which are normally distributed, with mean equal to the weight of the object placed on it, and variance σ2, which is unknown, and does not depend on the weight. Beatrice wishes to estimate σ2. She places on the scale an object whose weight is known to be exactly 50 lbs, getting a reading Y1. She repeats this independently n - 1 times, getting readings Y1, Y2,...,Yn. She is considering the following two estimators...
