The time it takes for a point to reach 0 displacement from maximum displacement is
of a cycle. Thus, one period (
) will take
.
The frequency is simply
.
The speed is given by:
For the 5.0Kg block with the force of 15 Newton, the coefficient of static friction (μ) comes out to be 0.306. Applying the formula F = μmg.
Static friction acts on stationary body/body at rest. Let μ be the coefficient of static friction between the block and the horizontal floor.
Using the formula: F = μmg
Where,
F = Force , m= mass of the block and g = gravity.
and values of: m= 5.0Kg, F= 15.0N, g= 9.8m/s²
We can get: μ = F/(mg)
μ = 15/49
μ =0.306
Therefore, coefficient of static friction (μ) = 0.306.

I believe it would be A, (B) just because a women trains doesn't mean she'll bulk, the may become thinner, or more tone. No to C because You have to change up and make workouts more difficult to help improve your body, and no to D because a workout doesn't have to be strenuous, you can be careful and not crazy about working out and still help your body. hope this helped
