11. 1. A 5000 kg car in the parking lot2. A 50 kg table being pushed at 2 m/s3. A 40 kg person jogging at 6 m/s4. A 2 kg rabbit sprinting at 15 m/s12. False
Explicación
## Step1For question 11, we need to calculate the momentum of each object. The formula for momentum is:###
where
is momentum,
is mass, and
is velocity.## Step2Calculate the momentum for each object:1. A 5000 kg car in the parking lot:
2. A 40 kg person jogging at 6 m/s:
3. A 50 kg table being pushed at 2 m/s:
4. A 2 kg rabbit sprinting at 15 m/s:
## Step3For question 12, we need to understand the definition of impulse. Impulse is defined as the change in momentum of an object when a force is applied over a given distance. It is not the force exerted on an object over a given distance.
