Answer:
the speed of a jet plane = v = 12 m/s
Explanation:
jet plane that travels 48 meters East in 4 seconds?
<u>use the velocity as distance over time formula = v = d / t</u>
where:
t = 4 sec
d = 48 m
plugin values into the formula
v = <u> 48 m </u>
4 sec
v = 12 m/s
therefore,
the speed of a jet plane = v = 12 m/s
Answer: 1.77kg
Explanation:
Using the concept or hooke's law, the force (F) applied to a string is directly proportional its extension (e)
F=ke
K is the elastic constant
If the mass applied initially is 0.59kg i.e 5.9N force, we have
5.9=ke... (1)
If a second block is attached let's say 'm', its force will be 10m, and the extension will become 3e
10m = 3ke ... (2)
Dividing eqn 1 by 2,
5.9/10m = ke/3ke
5.9/10m = 1/3
10m = 5.9×3
m = 5.9×3/10
m = 1.77kg
A particle in uniform circular motion requires a net force acting towards the center of the circular path.
Objects or particles that are in circular motion are those objects that move along a circular path. This motion along a circular path can be uniform with constant angular rate of rotation and a constant speed, non-uniform with a changing rate of rotation and speed.
It means then that a particle in uniform circulation motion moves in a circle with a constant speed, though with a changing velocity. It is because of this changing velocity that makes the particle to experience acceleration.
The particle in uniform circular motion will also experience centripetal acceleration which will cause and makes it maintain the uniform circular motion. This centripetal acceleration is the net force that causes the circular motion and is directed towards the center of the circular path.
Hence, a particle in uniform circular motion will require a net force directed towards the center of the circular path.
