Answer:
The arrow-apple combo will move with a velocity 3.6 m/s to the right.
Explanation:
Use the law of conservation of momentum to solve this problem. In this case the law can be written as follows:

from which the desired velocity can be isolated:

The arrow-apple combo will move with a velocity 3.6 m/s to the right.
Answer:
Explanation:
Consider another special case in which the inclined plane is vertical (θ=π/2). In this case, for what value of m1 would the acceleration of the two blocks be equal to zero
F - Force
T = Tension
m = mass
a = acceleration
g = gravitational force
Let the given Normal on block 2 = N
and 
and the tension in the given string is said to be 
When the acceleration 
for the said block 1.
It will definite be zero only when Force is zero , F=0.
Here by Force, F
I refer net force on block 1.
Now we know

It is known that if the said
,
then Tension
,
Now making 
So If we are to make Force equal to zero

density is correct hope this helps
