If two objects are moving towards each other with speeds of 40 m/s and 60 m/s, how long will it take for them to collide if they are 200 m apart?
Correct Answer: 2 seconds
- Step 1: Identify the speeds of the two objects. One is moving at 40 m/s and the other at 60 m/s.
- Step 2: Calculate the relative speed by adding the speeds of both objects together: 40 m/s + 60 m/s = 100 m/s.
- Step 3: Determine the distance between the two objects, which is given as 200 m.
- Step 4: Use the formula for time, which is Time = Distance / Speed.
- Step 5: Plug in the values: Time = 200 m / 100 m/s.
- Step 6: Calculate the time: 200 m / 100 m/s = 2 seconds.
