Yea I would love to help u
Answer:
Explanation:
In physics, there are two types of physical quantities namely the fundamental and the derived quantities. Fundamental quantities are independent quantities on which derived quantities depends on. Length, mass and time are examples of fundamental quantities.
The SI unit of length is meters. A meter is a multiple unit. Its submultiple units are centimetres (10⁻²metres), kilometres (10³metres), decimetres (10⁻¹metres) etc
The SI unit of mass is kilogram (kg). The only sub multiple unit used in real-life situation is grams.
1 kg = 100 grams
The SI unit of time is seconds. The multiple units are the minutes, hours, weeks, days and years.
1 minute = 60 seconds
1 hour = 3600 seconds
1 day = 24 * 3600 = 86,400 secs

Explanation:
From the question we are told that
The mass of the bag is 
The normal force experienced is 
The maximum acceleration of the bag is 
Generally this normal force experience by the bag is mathematically represented as
=> 
=> 
=> ![\theta = cos^{-1}[0.9183]](https://tex.z-dn.net/?f=%5Ctheta%20%20%3D%20cos%5E%7B-1%7D%5B0.9183%5D)
=>
Generally for the bag not to slip , it means that the frictional force is equal to the sliding force
Hence 
is mathematically represented as
While 
is mathematically represented as
So
=> 
=>
Generally from the workdone equation we have that
Here 
is the work done by friction which is mathematically represented as
Here s is the distance covered by the bag
is zero given that velocity at rest is zero
and
so
=> 
substituting 2.55 m/s for v_i and 0.350 for \mu_k we have that
=>
M= Height of image/height of the object
If, M>1, then height of image>height of object.
And therefore, image is larger than the object.
