Answer:
0.15694 m
Explanation:
m = Mass of block =
v = Velocity of block = 11.2 m/s
k = Spring constant = 110 N/m
Here the kinetic energy of the fall and spring are conserved
The amplitude of the resulting simple harmonic motion is 0.15694 m
What is "Motion?"
1 answer:
In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. One can also speak of motion of images, shapes, and boundaries.
Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion. For example; motion of a car on highway.
In physics, motion is the change in position of an object with respect to its surroundings in a given interval of time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, and speed. An object's motion cannot change unless it is acted upon by a force.

Answer:
The velocity of the boat 15 seconds later is 5.6 meters per second.
Explanation:
We assume that sailboat can be modelled as particle, so that we use solely translations equations. It is noticed that the sailboat is move by action of the wind and drag force of the water is opposed to such force, but the last force has a greater magnitude than the first one, meaning that net force is less than zero.
From Newton's Laws we have the following equation of equilibrium for the sailboat:
(Eq. 1)
Where:
- Force from the wind exerted on the sailboat, measured in newtons.
- Drag force of the water, measured in newtons.
- Mass of the sailboat, measured in kilograms.
- Net acceleration of the sailboat, measured in meters per square second.
If we know that ,
and
, then the net acceleration of the sailboat is:
If sailboat decelerates uniformly, then we can get the final velocity of the boat by using this equation of motion:
(Eq. 2)
Where:
,
- Initial and final velocities of the sailboat, measured in meters per second.
- Time, measured in seconds.
If we get that ,
and
, then the final velocity of the sailboat is:
The velocity of the boat 15 seconds later is 5.6 meters per second.
Answer:
The distance is 3.1 m
Explanation:
The position vector of the fly relative to the corner of the wall is
r = (3.1, 0.5).
The distance of the fly from the corner will be calculated as the magnitude of the vector "r"
magnitude of vector
Since the numbers to be added have only one decimal place 3.<u>1</u> and 0.<u>5</u>, the result of the sum will have to have one decimal place. The result of the square root will also have one decimal place.
