Answer:
The tension in the cord is 
Explanation:
Given:
M = mass
b = radius
R = spool of radius
The equation is:
 (eq. 1)
 (eq. 1)
The sum of forces in y:
∑Fy = Mg - T = Ma

Replacing in eq. 1

 
        
                    
             
        
        
        
Answer:
The value of tension on the cable T = 1065.6 N
Explanation:
Mass = 888 kg
Initial velocity ( u )= 0.8 
Final velocity ( V ) = 0
Distance traveled before come to rest = 0.2667 m
Now use third law of motion  =
 =  - 2 a s
 - 2 a s
Put all the values in above formula we get,
⇒ 0 =  - 2 × a ×0.2667
 - 2 × a ×0.2667
⇒ a = 1.2 
This is the deceleration of the box.
Tension in the cable is given by T = F = m × a
Put all the values in above formula we get,
T = 888 × 1.2 
T = 1065.6 N
This is the value of tension on the cable.

The magnitude (in N) of the force she must exert on the wrench is 150.1 N.
<h3>
Force exerted by the wrench</h3>
The force exerted by the wrench is calculated using torque formula as follows;
torque, τ = F x r x sinθ
where;
- F is the applied force
- r is the perpendicular distance if force applied
F =  τ /(r sinθ)
F = (39) / (0.3 sin 60)
F = 150.1 N
Thus, the magnitude (in N) of the force she must exert on the wrench is 150.1 N.

It’s easier to lift the wheelbarrow when the load is near the front because there isn’t any pressure near the back where the handles are.
