The acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².
The given parameters;
- <em>initial velocity of the engine, u = 1341 m/s</em>
- <em>final velocity of the engine, v = 7600 m/s</em>
- <em>time of motion, t = 2 minutes = 2 x 60 s = 120 s</em>
The acceleration of the SRB and main engine is calculated as follows;
Thus, the acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

In order to calculate the temperature, we need to know that temperature and pressure are directly proportional, that is, if the pressure increases, the temperature (in Kelvin) also increases in the same proportion.
So, first let's convert the temperature from Celsius to Kelvin, by adding 273 units:
Then, let's calculate the proportion:
Now, converting back to Celsius, we have:
So the temperature would be 166.5 °C.
Answer:
The value of tangential acceleration 40
The value of radial acceleration
Explanation:
Angular acceleration = 50
Radius of the disk = 0.8 m
Angular velocity = 10
We know that tangential acceleration is given by the formula
Where r = radius of the disk
= angular acceleration
⇒ 0.8 × 50
⇒ 40
This is the value of tangential acceleration.
Radial acceleration is given by
Where V = velocity of the disk = r
⇒ V = 0.8 × 10
⇒ V = 8
Radial acceleration
This is the value of radial acceleration.
