You are running from a zombie with a velocity of 2.5 m / s. If you run for 1500 meters and have a mass of 61.4 kg, how much work have you done?
To calculate the work done while running from a zombie, we need to use the formula:
Work (W) = Force (F) x distance (d) x cosine(theta)
In this case, the force can be calculated using Newton's second law of motion:
Force (F) = mass (m) x acceleration (a)
First, let's determine the acceleration of the zombie chasing you. Acceleration is the rate of change of velocity, given by:
Acceleration (a) = Change in velocity / Time taken
Since the velocity of the zombie is given as 2.5 m/s, and you are running away, your velocity is 0 m/s (assuming you are not moving). Therefore, the change in velocity (2.5 - 0) is also 2.5 m/s.
Now, let's look at the time taken. Unfortunately, the problem statement doesn't provide any information about the time, so we cannot determine the acceleration accurately. Without the acceleration, we cannot calculate the force or the work done.
Therefore, with the given information, it is not possible to determine how much work you have done while running from the zombie.
