Answer:
a force and a movement in the same direction as the force.
Explanation:
The vertical component of
this acceleration will be:
A= mgsin^2 <span> θ</span>
The downward fforce exerted by the hamster on the block and
on the scle will be
F = -ma
The reading will be like this:
Reading = Mg + mg sin^2 θ
= (0.820) (9.8) +
(0.190) (9.8) sin^2 (0)
<span>Reading = 8.036 N</span>
Answer:
The total momentum of the universe is always the same and is equal to zero. The total momentum of an isolated system never changes. Momentum can be transferred from one body to another.
Momentum quantifies how likely an object is to stay in motion. Momentum can also be explained using the equation, p=mv, where p is equal to momentum, m is equal to mass, and v is equal to velocity.

Explanation:
Step 1: Determine the equation of speed of an object moving in an harmonic motion
Speed of moving in an harmonic motion is given by
![v = \sqrt{\frac{k}{m} (A^2 -x^2)} \\](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%5Cfrac%7Bk%7D%7Bm%7D%20%28A%5E2%20-x%5E2%29%7D%20%5C%5C)
Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.
In this question ,
because only at this position maximum speed occurs
So the simplified equation becomes -
![v = \sqrt{(\frac{k}{m} * A)}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%28%5Cfrac%7Bk%7D%7Bm%7D%20%2A%20A%29%7D)
OR
![m = \frac{kA^2}{v_(max)^2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7BkA%5E2%7D%7Bv_%28max%29%5E2%7D)
Substituting the given values in above equation we get -
Assume spring constant is
N/m
![m = \frac{16 * 0.14}{2} \\m = 1.12](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B16%20%2A%200.14%7D%7B2%7D%20%5C%5Cm%20%3D%201.12)
Mass of banana is
Kg
