The formula for inertia is mass multiplied by speed.
For object W: Inertia = 6.5 kg * 18 m/s = 117 kg*m/s
For object X: Inertia = 3.0 kg * 15 m/s = 45 kg*m/s
For object Y: Inertia = 11.5 kg * 9 m/s = 103.5 kg*m/s
For object Z: Inertia = 5.0 kg * 6 m/s = 30 kg*m/s
Therefore, object W has the greatest inertia with 117 kg*m/s.
So the answer is:
B) W
A Student is investigating the inertia of several objects. she recorded her data in a table.
object: w,x,y,z.
