Explanation:
If this dish has the form of a concave upward parabola and its vertex 
is at the origin, its corresponding equation is:
Where:
is the radius, which can be found by dividing the diameter 
by half. Hence 
is the depth
is the vertex of the parabola, where its base is
Finding :
Finally:
This is where the the receiver should be placed
A soccer ball takes 20 s to roll 10 m.
Speed of the soccer ball
= 10/20 m/s = 1/2 m/s
Hi there!
On a level road:
∑F = Ff (Force due to friction)
The net force is the centripetal force, so:
mv²/r = Ff
Rewrite the force due to friction:
mv²/r = μmg
Cancel out the mass:
v²/r = μg
Solve for v:
v = √rμg
v = √(25)(9.81)(0.8) = 14.01 m/s
