It’s mass is 100 kg, because if you divide both numbers, you get 100
In order to solve the problem, it is necessary to apply the concepts related to the conservation of momentum, especially when there is an impact or the throwing of an object.
The equation that defines the linear moment is given by
where,
m=Total mass
Mass of Object
Velocity before throwing
Final Velocity
Velocity of Object
Our values are:
Solving to find the final speed, after throwing the object we have
We have three objects. For each object a launch is made so the final mass (denominator) will begin to be subtracted successively. In addition, during each new launch the initial speed will be given for each object thrown again.
That way during each section the equations should be modified depending on the previous one, let's start:
A)
B)
C)
Therefore the final velocity of astronaut is 3.63m/s
Acceleration = (final velocity-initial velocity)/time
5 = (v-0)/20
v = 100m/s
The dependent variable in this experiment is the mass of each liquid.
Density is the ratio of mass to volume of a substance. In this experiment, since the volume of each liquid is given, to get density, mass of each quantity must be known which is the outcome.
Density also depend on the mass of a substance and density can easily be identified by mass if all the substance in question have the same volume.
In this experiment, all the liquid have the same volume. Since the student want to list them in order from the least dense to the most dense, how dense the liquid are will be a function of the differences in liquid mass.
The least dense liquid will float. That is, will be at the top most of the container. While the most dense will be at the bottom of the container.
Therefore, the dependent variable in this experiment is the mass of each liquid
