Hi, so on this question, we have that yuki puck with the mass of 0 .16 kilograms is pushed with the force of 0 .25 meters.
00:20
In the initial velocity, you is zero meters a second because what was at rest.
00:28
So if you're part a, one to find the position and speed of the puck at heat goes two seconds.
00:33
So first of all to find the position.
00:37
The work done by the force and pushing the puck because of the change the kinetic energy produced.
00:45
This is the walk done first time distance.
00:48
This is the walk down first time distance and the kinetic energy is half mb squared.
00:52
So half mv squared.
00:54
And v is the final velocity.
00:56
So this is the final kinetic energy minus and that's where m u squared.
01:00
Used in charge of lous t.
01:03
So there is the final kinst kinetic energy minus t...
