Answer:
I'm pretty sure it is (2,0)
20 times 5 is 100. We can multiply 2*5 and get 10, then add another zero to make it easier.
Answer:

Step-by-step explanation:
Recall the formula:

We apply this formula to simplify 
This implies that:



This simplifies to


Given that,
velocity, v = 7.8 ft/s
Radius, r = 1.25 ft
To find,
a. What is the acceleration of the bucket?
b. What is the velocity if the acceleration is 25 ft/sec²?
Solution,
(a) The centripetal acceleration is given by :

Put v = 7.8 ft/s and r = 1.25 ft

(b) Put a = 25 ft/s² to find velocity.

Hence, this is the required solution.
8.6 because 8 is bigger than 6
