Yes. According to the coach's mathematical criteria, Tommy had a great season.
Sadly, Tommy doesn't even know it. His tone-deaf coach decided to describe success in terms that are absurd for 7-yr-olds, as well as for most of their parents.
Explanation:
The Hubble telescope was launched in 1990, in the low Earth orbit and remains in operation. It was built by NASA with contributions from European Space Agency. There was a serious problem with the optical system and the analysis showed that the cause is the primary mirror that had been polished to the wrong shape, introducing spherical aberration. It was solved by sending servicing mission in 1993, by installing a set of specialized lenses to correct the flawed main mirror in the telescope. Including this, there have been total five astronaut servicing mission to Hubble.
The mass of this bag of cement in S.I. units (kg) is equal to 0.062 kilograms.
<u>Given the following data:</u>
- Mass of cement = 62 grams.
To calculate the mass of this bag of cement in S.I. units (kg):
<h3>How to convert to
S.I. units.</h3>
In Science, kilograms (kg) is the standard unit of measurement or S.I. units of the mass of a physical object. Thus, we would convert the value of the mass of this bag of cement in grams to kilograms (kg) as follows:
<u>Conversion:</u>
1000 grams = 1 kilograms.
62 grams = X kilograms.
Cross-multiplying, we have:
X = 
X = 0.062 kilograms.

Answer:
<h3>38,673.9N</h3>
Explanation:
According to newton's second law:
Force = mass * acceleration
Given
Mass = 873kg
acceleration = 44.66m/s²
Magnitude of the force is expressed as;
F = ma
F = 873 * 44.6
F = 38,673.9N
<em>Hence the magnitude of the net force exerted on the dragster during this time is 38,673.9N</em>
The spring's elastic potential energy is converted into elastic potential energy of the boy.
Potential energy = elastic energy
mgh = 1/2 kx²
k = (2 * 25 * 9.81 * 0.5) / 0.4²
k = 1533 N/m
We will apply
2as = v² - u², with u = 0
a = F/m
F = kx
a = kx/m
v = √(2 x 0.4 x (0.4 x 1533 / 25))
v = 4.43 m/s
