Adding thermal energy
Performing work on the system
Answer:
law of Action and Reaction F = 2250 N
Explanation:
The tractor and the trailer are two bodies that interact, therefore, by the law of Action and Reaction, the force that one applies on the other is equal to the force that the second body (trailer) applies on the first (tractor), but with opposite direction
F = 2250 N
directed from trailer to tractor
Answer:
Part a)
When spring compressed by 2 cm
H = 1.47 m
Part b)
When spring is compressed by 4 cm
H = 5.94 m
Explanation:
Part a)
As we know that the spring is compressed and released
so here spring potential energy is converted into gravitational potential energy at its maximum height
So we will have
so we have
Part b)
Similarly when spring is compressed by 4 cm
then we have
so we have
Answer:
Free-body diagrams are defined as the diagram that represents the direction and magnitude of all forces that act on an object.
There are some limitations of the free-body diagrams, that are:
- The free-body diagram is based on coordinate system that increases the complexity of the diagram.
- There are lot of forces acting on an object such as friction, gravity, drag, tension, and normal force and to calculate the end result, it is important to determine the correct direction of all the forces otherwise wrong direction of any one of the force can give the wrong answer.
- Free-body diagrams do not depend on the size and shape of the body, that is why unable to calculate the rotation and torque.
Answer:
4) the same as Charlie's.
Explanation:
They both make one full circuit (2π radians) of the merry go round in the same amount of time, therefore their angular speed is the same
