Question

8. A dog runs with an initial speed of 7.5 m/s on a waxed floor. It slides to a stop in 15 seconds. What is the acceleration?

Answers

GPT 3.5
To find the acceleration, we can use the equation:

acceleration = (final velocity - initial velocity) / time

Given:
Initial velocity (u) = 7.5 m/s
Final velocity (v) = 0 m/s (the dog comes to a stop)
Time (t) = 15 seconds

acceleration = (0 - 7.5) / 15
acceleration = -7.5 / 15
acceleration = -0.5 m/s^2

Therefore, the acceleration of the dog on the waxed floor is -0.5 m/s^2.
