Change in Momentum and Impulse Practice Test

A $1500,\text{kg}$ rocket in deep space starts at rest and fires its engine producing a constant $9000,\text{N}$ thrust for $6.0,\text{s}$. External forces are negligible. Using the given data, determine the change in momentum of the system.

A $1500\ \text{kg}$ car moving east at $12\ \text{m/s}$ is brought to rest by a collision in $0.30\ \text{s}$. Using the given data, determine the change in momentum of the car.
