Question

she carries one type of newspaper in a bag attached to her bicycle each time she rides.
mass of newspaper bag
newspaper | mass (kg)
beginning of the week | 5
holiday | 8
mid - week | 6
special edition | 7
weekend | 3
brianna’s bicycle has the same acceleration at the start of each of her deliveries. order the newspapers to show the size of the force she applies to the bicycle when starting each delivery.
larger force
beginning of the week
holiday
mid - week
special edition
weekend

Explanation:

To determine the force applied, we use Newton's second law, \( F = ma \). Since acceleration \( a \) is constant, force \( F \) is directly proportional to mass \( m \). So we order the masses from largest to smallest, which will correspond to the force order (larger mass → larger force).

Step 1: List the masses

• beginning of the week: \( 5 \, \text{kg} \)
• holiday: \( 8 \, \text{kg} \)
• mid - week: \( 6 \, \text{kg} \)
• special edition: \( 7 \, \text{kg} \)
• weekend: \( 3 \, \text{kg} \)

Step 2: Order masses from largest to smallest

\( 8 \, \text{kg} \) (holiday) > \( 7 \, \text{kg} \) (special edition) > \( 6 \, \text{kg} \) (mid - week) > \( 5 \, \text{kg} \) (beginning of the week) > \( 3 \, \text{kg} \) (weekend)

Answer:

From larger force to smaller force: holiday, special edition, mid - week, beginning of the week, weekend
