Answer:
3.14 m/s
Explanation:
We are given that
Mass of object=1.1 Kg
Spring constant=160 N/m
a.We have to find the amount by which the spring is stretched from its unstrained length(it means x)
We know that F=kx ,
b.When an object is pulled straight down by an additional distance 0.26 m and released from rest.
x=0.26 m
We have to find the speed with which the object passes through its original position on the way up.
(Law of conservation of energy)
Substitute the values then we get
Hence, the speed of an object with which the object passes through its original position on the way up=3.14 m/s
Answer:
A. Yes its possible by employing Pythagoras theorem we can see that similar triangles can have similar hypotenuse but different length
B.no it's not possible also from Pythagoras of they have same components it must be the same triangle
Magnitude of acceleration = (change of speed) / (time for the change) =
(12 m/s - 0) / (3 sec) =
12/3 = <em>4 m/s²</em>
What's a challenge question ? Have we all passed the event horizon
and been spaghettified without knowing it ?
After all the ice melts the temperature of water inside the beaker starts rising. As the temperature of water inside beaker is less than temperature of surrounding.So heat transfer from surrounding to water inside beaker because we heat transfer from high temperature to low temperature.
Answer:
α= 15.4[rad/s^2], 500 [rev/min]
Explanation:
La aceleración angular constante esta definida por la siguiente ecuación:
Para poder llegar a las 2000 [revoluciones /min] estando en 1500 [rev/min], la cuchilla tuvo que incrementar su numero de revoluciones a 500 [rev/min]. Mientras aceleraba.
