A skateboarder starts from rest and maintains a constant forward acceleration of 0.50 meter per second squared for 8.4 s. what i

myrzilka [38]

Answer-

The rider’s displacement during this time is 17.01 m

Solution-

As we know,

$s= ut + \frac{1}{2}at^{2}$

Where s = displacement,

u= initial velocity = 0, as the rider starts from rest

a= acceleration = 0.5 m/s²

t= time taken = 8.4 s

Putting the values,

$s = (0)(8.4) + \frac{1}{2} (0.5)(8.4)^{2} = 17.64 \ m$

Step-by-step explanation:

To find the surface area of a cone, one uses the following formula,

$A=(\pi)(r)(r+\sqrt{h^2+r^2}})$

Where (r) is the radius of the base of the cone, and (h) is the height of the cone, ( $\pi$ ) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
