The Ballistic Pendulum #

2 different ways to measure a projectile

Watch the youtube video

For the theory section: #

How to find initial velocity:

Measure the total height

And the length in the x direction

Kinematics

Then find total time

Solve for t

Plug back in

To make the calculations:

Horizontal measurements

Both of these together is x total

Then measure vertical

Add both together to get y total

Data is already in the document

Calculate the muzzle speed using the kinematics equations

Second part of the lab has the pendulum down so the ball launches into the pendulum.

The change in height of the pendulum is measured.

$h$ is the difference in height of the pendulum’s center of mass

Solve for $V_o$

For the second part

Initial height is of above the platform, final is the height after launch. Change in height is the difference between them.

HW questions #

Number 4

We want to know the speed of the Earth around the Sun and Io around Jupiter.

Number 5

Solve for $x$

Number 6

The two objects are traveling perpendicular

Both speeds are relative to earth and its asking for the rivet’s speed relative to the satellite

Before they collide

After they collide

Smashed like a pancake, they want to know time of interaction

What is the average force?
