<span>a.
the force in the direction of movement
Fx = F x cosA*
Fx = 12 x cos25*
Fx = 10.88
m x a = 10.88
a = 10.88/5
a= 2.18 m/s^2
b.
when the block will be lifted off the floor and when the vertical component
Fy = mg
Fy = F x sin25*
Fy= 5 x 9.8
Fy= 115.94 N
c.
if Fx = ma
a = 115.94/5
a= 23.19 m/s^2
hope it helps

<u>Analysing the Question:</u>
We know that equilibrium is the state of a body when it has equal and opposite forces being applied on it
In this case, a net downward force of 496N is being applied and a net upward force of (106 + 106 + 142 + x) N
<u>Finding the missing force:</u>
Since we have to achieve equilibrium, the net upward forces have to be equal to the net downward forces
So, (106 + 106 + 142 + x) = 496
354 + x = 496
x = 496 - 354
x = 142 N
Therefore, the missing force is 142 N
I looked up the question and got D- a vacuum
Answer:
c. because A will land first becuase its heavier
and D.

Complete Question
The complete question is shown on the first uploaded image
Answer:
The velocity is
Explanation:
From the question we are told that
The distance of the rooster from farm house is 
The height of the rooster from the ground is 
The angle at which the alarm clock is thrown is 
Let the velocity at which the alarm clock is thrown be v
So the horizontal component of v is mathematically represented as

The distance covered by the alarm clock toward the horizontal direction at velocity v is

=> 
=> 
substituting for 

=> 
Considering the motion of the alarm clock in the vertical direction
So the vertical component of v is mathematically represented as

The distance covered in the vertical direction is mathematically evaluated as follows
From the equation of motion we have


Recall 
So

substituting for 

=> 

Now

So

=>
