I think it is d if not then im sorry
Answer:
Xcm = (6 * 0 + 4 & 3 + 2 * 0) / 12 = 1
Ycm = (6 * 0 + 4 * 0 + 2 * 3) / 12 = 1/2
(Xcm , Ycm) = (1 , 1/2)
Using definition of center of mass

Q=46830 J
Total Entropy change of system
Answer:
6 km
Explanation:
speed of Aaron, v = 8 km/hr
speed of Sam, v' = 6 km/hr
time 15 min = 0.15 hr longer than the other
Let the distance covered by both of them is d.
Let the time taken by Aaron is t and the time taken by Sam is t + 0.25
use the formula of distance = speed x time
For Aaron:
d = 8 x t ..... (1)
For Sam:
d = 6 ( t + 0.25) ..... (2)
From (1) and (2)
8 x t = 6 (t + 0.25)
8 t = 6t + 1.5
2t = 1.5
t = 0.75 hour
So, the distance traveled by both is 8 x 0.75 = 6 km.
