Practice Questions
Question 1
Which of the following scenarios demonstrates a system where the total momentum is conserved?
Question 2
A soccer ball with a mass of $0.45 \text{ kg}$ is kicked with a velocity of $18 \text{ m/s}$ towards the north. What is the magnitude and direction of its momentum?
Question 3
How does increasing the time over which a force is applied affect the change in momentum of an object, assuming the average force remains constant?
Question 4
A $0.15 \text{ kg}$ baseball is thrown with a velocity of $40 \text{ m/s}$. A $0.06 \text{ kg}$ tennis ball is thrown with a velocity of $70 \text{ m/s}$. Which ball has greater momentum?
Question 5
Two carts, one with mass $m$ and another with mass $2m$, are moving towards each other with the same speed $v$. If they collide and stick together, what is the final velocity of the combined system?
