Hi there.
00:01
So for this problem, we have a rocket that has an initial mass of 125 kilograms.
00:13
And we also know that it produces a constant vertical force of 1 ,070 and 120 meters.
00:30
And, well, at first we need to calculate the initial acceleration of the rocket.
00:40
To calculate this initial acceleration, we should simply use newton's second law that it states that the force that is acting on a body is equal to the mass of the body times the acceleration.
00:54
So if we want to find the acceleration that in this case, it's going to be the force or the mass.
01:04
Which is 1 ,720 newton over 125 kilograms.
01:18
This is equal to putting all these values into the calculator, obtain 13 .76 meters per second square.
01:39
So this is the acceleration, the initial acceleration of the rocket.
01:46
Now, we know that there is an electrical power supply that rests on the floor inside the rocket, which we're going to call m.
02:04
And has a mass, well, we don't know the mass, but we know that its weight is 15 .4.
02:17
5 mutants.
02:23
And we want to determine how hard does the floor push on the power supply.
02:32
So we first need to draw all the forces that are up in on this body.
02:37
We are drawing the axis.
02:40
So we know that the forces that are acting are the normal force perpendicular to this surface, the weight.
02:52
And we also know that the rocket is moving upward with an acceleration a, so that we will have that the soon, when we apply newton's second law, in the case we only have horses in the y component...
