Answer:
a
b
c
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
=>
The answer to your question is 12 degrees because you subtract 42 degrees minus 30 degrees to get 12 degrees
Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
There are several actions that can be used to increase the action force of a canoe that is moving through water. One can increase the rate of striking or strike harder than before with a bigger paddle. Using a lighter canoe can also be helpful for increasing the speed. I hope the answer comes to your help.
