Actually Welcome to the concept of distance formula.
Distance formula ==>
so applying this we get as,
D = underoot (9)^2 + (-5)^2
==> D = 10.29 units
distance = 10.29 units

Explanation:
The distance s as a function of time can be written as:
The rate of change is the derivative of d with respect to time:
The time t when the track has been traveling for 81 miles is given by:
Using t in the previous equation gives:
(a) 0.74 m/s^2
Explanation:
There are two forces acting on the skier: the component of the weight parallel to the slope, which acts downward, and the frictional force, which acts upward along the incline.
The component of the weight parallel to the inclined plane is:
where m is the mass of the skier, and
.
The frictional force is instead
is the coefficient of friction for waxed wood on wet snow.
If we apply Newton's second law, we can write that the net force must be equal to the product of mass per acceleration:
And symplifying m, we can find the acceleration:
(b)
Explanation:
This time, the skier is moving at constant velocity. Therefore, the acceleration is zero (a=0) and Newton's second law becomes:
By simplifying, we get
From which we can find the angle at which the skier could coast at a constant velocity:
