What is the formula for finding your maximum heart rate

1 answer:

8 0

According to the American Heart Association, the broad,
approximate guideline for your MAXIMUM heart rate is:

   -- take 220
   -- subtract your age
   The unit is "beats per minute".

But there are many things that have an effect on this number.
A few of them are:
-- your age
-- your weight
-- any medicines you're taking
-- HOW you measure your heart rate.

If you're planning any REGULAR activity that will play with
your heart rate, you really ought to discuss it with your doctor
before you jump in.

Answer:

v(7) = 52.915 m/s

Explanation:

First, find the value for acceleration.

F = ma

100 = .5 * a

a = 200 m/s²

Next find the velocity at x = 7 using kinematic equations.

v² = v₀² + 2a(Δx)

v² = (0)² + 2(200)(7)

v = $\sqrt{2800}$

v = 52.915 m/s

Answer:

$a=3m/s^2$

Explanation:

If we have a net force F acting on a body of mass m it will experiment an acceleration a. Newton's 2nd Law gives us the relation between these quantities: F=ma.

In our case, we want to calculate the acceleration, so we write:

$a=\frac{F}{m}$
