Here, an object with a mass of 0 .4 hundred kilograms is attached to the spring with a constant of 8 newton per meter.
00:14
And the amplitude is 11 .6 centimeters.
00:23
So first, we have to calculate maximum speed.
00:29
Let's calculate angular frequency.
00:32
That is for 0 .47 radiance per second and now as we know maximum speed is amplitude times this angle frequency so this maximum speed is 51 .9 centimeters per second now let's move on to the next question we have to determine maximum acceleration that's 200 and 32 centimeters per square second.
02:08
Now in question c, we have to calculate value of the speed when the object is at 9 .60 centimeters from equilibrium.
02:25
Kinetic energy plus potential energy of the spring at this moment equals to maximum kinetic or maximum potential potential energy of the spring at this moment equals to maximum kinetic or maximum potential.
02:37
Energy.
03:07
Let's calculate it.
03:15
Here we must convert centimeters to meters.
03:46
That is 0 .291 meters per second, which is 291 centimeters per second.
04:01
Let's move on to question d...
