Ballistic Pendulum Example Problems Quiz

What are the two main principles used in solving ballistic pendulum problems?

• Electromagnetism and Optics

• Newton's Laws and Thermodynamics

• Conservation of Momentum and Conservation of Energy

• Kinematics and Dynamics

In the first example, what is the initial unknown variable that needs to be determined?

• The gravitational force

• The velocity of the bullet

• The height the pendulum rises

• The mass of the pendulum

How is the velocity of the bullet and pendulum system calculated after the collision in the first example?

• By using the formula for kinetic energy

• By applying the conservation of momentum

• By using the formula for gravitational potential energy

• By applying the conservation of energy

In the second example, what is the main goal of the problem?

• To calculate the mass of the bullet

• To find the velocity of the bullet

• To determine the change in height of the pendulum

• To measure the time of flight

What is the initial step in solving the second example problem?

• Using conservation of energy

• Using conservation of momentum

• Calculating the gravitational force

• Measuring the pendulum's length

In the third example, what is unique about the bullet's interaction with the pendulum?

• The bullet passes through the pendulum

• The bullet misses the pendulum

• The bullet embeds in the pendulum

• The bullet bounces off the pendulum

What is the final calculation needed in the third example problem?

• The time taken for the pendulum to stop

• The velocity of the bullet after passing through

• The change in height of the pendulum

• The mass of the pendulum

What is the velocity of the pendulum after the bullet passes through it in the third example?

• 4.50 meters per second

• 5.25 meters per second

• 7.68 meters per second

• 3.12 meters per second

What is the key takeaway from the video regarding solving ballistic pendulum problems?

• Ignore the velocity of the bullet

• Focus only on the mass of the pendulum

• Understand when to use conservation of energy or momentum

• Always use conservation of energy first
