You have done 43.9 joules of work to lift the can.
Answer:
The velocity = 5.82[m/s], Tension = 1.78 [N]
Explanation:
We can solve this problem using the principle of energy conservation and Newton's second law.
Here we can find an attached image of the pendulum with a free body diagram, where we can see the forces acting over the pendulum.
The initial data are:
The pendulum is released when the string is at 90° with respect to the vertical axis. Therefore the initial velocity is zero = 0, and the initial kinetic energy will be zero also.
The expression that defines the kinetic energy and the work is the following equation.
We take the reference point where the pendulum is matching the vertical axis. At this point the potential energy is zero and all the potential energy has been transformed into kinetic energy.
Now analyzing once again the expression deducted, we have:
In the free body diagram, we can see the forces and the equation to find the tension T. Especial attention must be seen to notice that the acceleration to find the tension in the equation should be the normal acceleration.
The normal acceleration is defined by:
Clearing the tension T, this value is 1.78 [N]
Answer:
Speed Unchanged.
Explanation:
As work is defined as a product of force over a distance. If the distance in altitude is constant = 500km, there's 0 change in distance and force, no work would be done by the gravitational force.
Since potential energy of the satellite is unchanged, unless there's additional internal energy source, the kinetic energy would remain unchanged, so would its speed.
The answer is that "elements are a single atom and compounds are a mixture of two elements or more." Elements are atoms that have protons, neutrons, and electrons. Compounds are mixtures with two or more elements.
Hope this helps.
