Answer:
1.73 m/s²
Explanation:
Given:
Δx = 250 m
v₀ = 0 m/s
t = 17 s
Find: a
Δx = v₀ t + ½ at²
250 m = (0 m/s) (17 s) + ½ a (17 s)²
a = 1.73 m/s²

Setting up an integral of
rotation is used as a method of of calculating the volume of a 3D object formed
by a rotated area of a 2D space. Finding the volume is similar to finding the
area, but there is one additional component of rotating the area around a line
of symmetry.
<span>First the solid of revolution
should be defined. The general function
is y=f(x), on an interval [a,b].</span>
Then the curve is rotated
about a given axis to get the surface of the solid of revolution. That is the
integral of the function.
<span>It all depends of the
function f(x), which must be known in order to calculate the integral.</span>
Answer:
Explanation:
Considering an object that moving about in a circular path, the equation for such centripetal force can be computed as:
The model for the person can be seen in the diagram attached below.
So, along the horizontal axis, the net force that is exerted on the person is:
Dividing both sides by "m"; we have :
Making "v" the subject of the formula: we have:
So, when = 0; the velocity is maximum
∴
Hence; the maximum walking speed for the person is
