Question

1. which object has the greatest inertia? (1pt)

a. a 10kg bicycle moving at 5m/s
b. a 500g baseball thrown at 30m/s
c. a 1000kg car at rest
d. a 50kg shopping cart

Explanation:

Step1: Recall inertia concept

Inertia is directly related to mass. Greater mass means greater inertia, regardless of motion state.

Step2: Compare masses

Convert 500g to kg: 500g = 0.5kg. Compare masses: 10kg (bicycle), 0.5kg (base - ball), 1000kg (car), 50kg (shopping cart).

Answer:

C. A 1000kg car at rest
