Hi guys, now in this film, my box is pulled with the force of 19 newton at the angle of 25 degree.
00:06
This is what we have, this is ground that i have.
00:09
And from there, our object is pulled with the force of f.
00:14
And this angle is what? this angle is 25 degree.
00:17
This angle is 25 degree.
00:20
And this force f is equal to, this is 19.
00:26
I need to find out acceleration if the kinetic friction mu of k is equal to it 0 .23.
00:33
Also we need to find out normal force there is a m g acting downwood as we noted this a normal is acting like this so this is normal i have and this is what m g and mass of this one is but this is 35 of g let's do a component will be like this second component will be like this so this is 95 sign of 25 degree sorry 90 times this is 25 degree and this is 90 cost of 25 degree when it moves in forward direction, friction will be worked like this.
01:10
This we call it what friction in backward direction.
01:13
And this is what f of k...
