Hello, the applying 8.
00:06
Second loop.
00:11
The net force equals mass times acceleration.
00:17
So one child applies 75 newtriens.
00:22
The other applies 90 in the opposite direction.
00:26
The mass of child and regan is 23 kilowatts.
00:31
So the net force on the wagon equals the mass of the wagon times its acceleration.
00:38
Now, we see that the 19 utene force is greater.
00:41
And so the body will move in this direction, which means that friction will act this way to oppose that.
00:50
And the friction is given as 12 newton.
00:53
So friction will pose the intended direction of motion, which is towards the left.
00:59
And so we now have 90, net force began 90 minus 75 minus 12.
01:09
So forces opposing the motion or in the opposite direction to our motion.
01:15
Are taken to be negative.
01:17
So this is the direction of motion that we have chosen...
