FORCES AND MOTION
2. Calculate the car’s speed (in metres per second, m s-1) at the various sectors around the
race track.
Sector 1. v = m s-1 Sector 2. v = m s-1
Sector 3. v = m s-1 Sector 4. v = m s-1
Sector 5. v = m s-1 Sector 6. v = m s-1
3. Multiply your answers for question 2 by 3.6 to convert them from m s-1 (metres per second)
to km hr-1 (kilometres per hour). Round your answer to the nearest km hr-1
.
Sector 1. v = km hr-1 Sector 2. v = km hr-1
Sector 3. v = km hr-1 Sector 4. v = km hr-1
Sector 5. v = km hr-1 Sector 6. v = km hr-1
4. Calculate the average speed (in km hr-1) for an entire lap by calculating the distance the
car travels during one lap, and the time it takes to complete the journey. Use the formula
for speed to determine your final answer.
