I believe the answer is free electrons
To find the x component use the following formula, where Ф = theta = the angle 'a' makes with the x axis.
Answer:
Pressure is equal in A, B, C and D
Explanation:
Pressure does not depends on the shape of the container
Pressure acting all direction
Answer:
In kinematics questions we need to separate the question into different parts if the acceleration changes. Here, there are three time intervals where acceleration is different.
1) a(t) = 96t. We can find the velocity function of the rocket by integrating the acceleration function. Then we can integrate again to find the position function.
'C' is the integration constant. We can find this constant by investigating the initial conditions.
We know that the rocket is initially at rest, so 'C' should be zero.
Again, the rocket started from ground zero, so C = 0.
We should conclude the first part by calculating the final position and final velocity of the rocket.
2) For the second part, the rocket is in free fall, so
The maximum height that the rocket reaches is when its velocity is zero.
So,
The maximum height is
The final positions for the part 2 is
3) With the parachute, the velocity is dropped from -276.4 to 16 in 5 s.
The rocket lands
50hz = 50 1/s
(0.1 m)(50 1/s)= 0.002 m/s
