So, to determine the acceleration, note that by newton's second law of motion, the net force is equal to the product of the mass and the acceleration.
00:33
For part a, if accelerating upwards, since net force is the sum of the forces acting on the object, then n -a is equal to the parent weight.
01:00
Plus the negative of the actual weight.
01:05
Note that apparent weight is noted that's positive since it is the same direction as the acceleration.
01:14
And we know that weight is the product of the mass and the acceleration due to gravity, such as six.
01:21
Now isolating a to the left side of the equation, since this is what we need, then our equation becomes the fits.
01:35
So simplifying, we have fixed.
01:42
Okay, if accelerating upwards, the apparent mass is measured by the scale is greater than the actual weight.
02:19
Then the apparent mass here is 180...
