Question

tony makes deliveries on his bicycle for a pizza shop. he always rides the same bicycle and places the objects he is delivering in the bicycles basket.

tony applies the same force to the bicycle each time he starts to ride. order the deliveries to show the size of the acceleration the bicycle will have each time tony leaves the pizza shop.

larger acceleration

smaller acceleration

Explanation:

Step1: Calculate mass for each delivery

• For 10 boxes of breadsticks: \(10\times100 = 1000\) g
• For 5 boxes of chicken wings: \(5\times400=2000\) g
• For 2 pizzas: \(2\times700 = 1400\) g
• For 20 salads: \(20\times200=4000\) g

Step2: Apply Newton's second law \(F = ma\) (since \(F\) is constant, \(a=\frac{F}{m}\), so smaller \(m\) gives larger \(a\))

Order masses: \(1000\lt1400\lt2000\lt4000\)

Answer:

Larger acceleration: 10 boxes of breadsticks, 2 pizzas, 5 boxes of chicken wings, 20 salads: Smaller acceleration
