<u>Given:</u>
Velocity of the dog, v = 5.4 m/s
Centripetal acceleration, a = 48.6 m/s2
<u>To determine:</u>
Radius of the path
<u>Explanation:</u>
The centripetal acceleration is related to the velocity and radius as:
a = v²/r
r = v²/a = (5.4 m/s)²/48.6 m/s2 = 0.6 m
Ans: Radius of the path is 0.6 m

B) Morrison and Franscioni's research done to create the Frisbee.
Answer: 0.335 moles
Explanation:
Given that,
Amount of moles of KBr solute (n) = ?
Volume of KBr solution (v) = 0.67 L
Concentration of KBr solution (c) = 0.50M
Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence
c = n / v
make n the subject formula
n = c x v
n = 0.50M x 0.67L
n = 0.335 moles
Thus, there are 0.335 moles of KBr in 0.67 L of a 0.50 M KBr solution
