Answer:
the mechanical advantage is 10
Explanation:
The computation of the mechanical advantage is as follows:
Mechanical advantage is
= Load ÷ Effort
where,
The Loan is equivalent to the weight i.e. 500 lb
And, the effort is equivalent to the force applied i.e. 50lb
So, the mechanical advantage is
= 500 ÷ 50
= 10
Hence, the mechanical advantage is 10
It important to assess flexibility both before and during a workout regimen because to assess flexibility progress.
<h3>What is a flexibility exercise?</h3>
Flexibility exercises, as the name implies, help to increase the stretch of the muscles, improving the range of motion. More flexibility is also important to help prevent possible post-workout soreness.
In this case we have that the reason to continue doing stretching before and during the exercises is about to assess flexibility progress.

Answer:
μ = mg/kx
Explanation:
Since the bock does not slip, the frictional force equals the weight of the block. So, F = mg. Now, the frictional force, F = μN where μ = coefficient of static friction and N = Normal force.
Now, the normal force equals the spring force F' = kx where k = spring constant and x = compression of spring.
N = F' = kx
So, F = μN = μkx
μkx = mg
So, μ = mg/kx
Answer:
The resultant vector is 1 m/s
Explanation:
The resultant vector is 1 m/s west based on triangle law of vector addition, when two sides of a triangle is represented by two vectors, the resultant vector is the third side of the triangle.
