8. A dog runs with an initial speed of 7.5 m/s on a waxed floor. It slides to a stop in 15 sec. What is the acceleration?
(10 Points)
O-7.5 m/s
-0.5 m/s2
O -7.5 m/s2
7.5 mi/hr

-0.5 m/s²

Explanation:

Step 1: Given data

Step 2: Calculate the acceleration of the dog

The acceleration (a) is equal to the change in the velocity over the time elapsed.

a = v - u / t

a = 0 m/s - 7.5 m/s / 15 s

a = -0.5 m/s²

part 1: which substance has a higher solubility?
