Final answer:
To find the time it takes Harry to skydive 678 meters at a constant velocity of 60.0 meters per second, divide the distance by the velocity, yielding an answer of 11.3 seconds (Option b).
Step-by-step explanation:
While skydiving, Harry falls toward Earth at 60.0 meters per second. If he falls at a constant velocity, how long will it take him to fall 678 meters? To determine the time it takes to fall a certain distance at a constant velocity, we can use the equation time = distance/velocity. So in this case, the time it would take Harry to fall 678 meters while skydiving at a constant velocity of 60.0 meters per second would be calculated as Time = Distance / Velocity, Time = 678 meters / 60.0 meters per second, Time = 11.3 seconds. Therefore, the correct answer is b) 11.3 seconds.
