Worked Solution & Example Answer:A: The following table shows the position of a moving object at uniform speed - Leaving Cert Chemistry - Question 4 - 2014
Step 1
Determine Average Speed
Answer
To calculate the average speed of the object over the first 4 seconds, we use the formula:
ext{Average Speed} = rac{ ext{Total Distance}}{ ext{Total Time}}From the table, the position at time 0 seconds is 0 m and at time 4 seconds is 20 m, thus:
- Total Distance = 20 m - 0 m = 20 m
- Total Time = 4 s
Substituting the values into the average speed formula yields:
ext{Average Speed} = rac{20 ext{ m}}{4 ext{ s}} = 5 ext{ m/s}Thus, the average speed of the object over the first 4 seconds is 5 m/s.
