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.

Answer:
51520J
Explanation:
The energy added to the piece of glass is also called heat needed to increase its temperature from 10°C to 50°C and it depends on the mass, specific heat capacity and the change in temperature.
Q=m.c.ΔT
Q=(2kg).(644J/(kg°C)).((50°C)-(10°C))
Q=51520J
Answer:
The acceleration of each mass is the same, and approximately equal to 
Explanation:
Notice that the mass of the whole system is: 30 kg + 40 kg = 70 kg
If we use a net force of 100 N on the combined system, we can find the acceleration imparted to the masses via Newton's second law:
It's by number of protons
<span>Acceleration is the rate of
change of the velocity of an object that is moving. This value is a result of
all the forces that is acting on an object which is described by Newton's
second law of motion. Calculations of such is straightforward, if we are given
the final velocity, the initial velocity and the total time interval. However, we are not given these values. We are only left by using the kinematic equation expressed as:
d = v0t + at^2/2
We cancel the term with v0 since it is initially at rest,
d = at^2/2
44 = a(6.2)^2/2
a = 2.3 m/s^2
