Ballistic Pendulum Quiz

What is the primary purpose of using a ballistic pendulum in this experiment?

• To measure the mass of the bullet

• To calculate the angle of deflection

• To determine the velocity of the bullet before impact

• To find the length of the pendulum

In the first step, which trigonometric function is used to find the adjacent side of the triangle formed by the pendulum?

• Secant

• Tangent

• Sine

• Cosine

What is the calculated change in height of the pendulum after the bullet lodges into it?

• 0.125 meters

• 0.265 meters

• 0.385 meters
