Vertical Marble Launcher

For this experiment you will use angles from 0 to 80 degrees.

Vertical marble launcher.

A marble with a speed of 2 0 m s rolls off the edge of a table 1 8 m high a how long does it take it to hit the floor. Three vectors v vx and vy form a right triangle. Easy to read protractor allows for precise measurements and calculations. If additionally α 90 then it s the case of free fall.

Attach one photogate to the marble launcher so that the marble breaks the light beam as it comes out of the barrel. B how far from the table will it hit the floor. A the time of flight assume down is positive. The launcher can launch at angles from 0 horizontal to 90 degrees vertical.

You can use a bubble level to align the. This design of a marble launcher uses a plunger that is pulled back inside of the barrel so that a compression spring begins to compress and create potential energy once released the spring drives the plunger through the barrel which forces the marble out of the barrel. Marbles can be launched from five different speeds at any angle between 0 and 90. The assignment was to create a projectile launcher to test if increasing the initial angle of an object marble would increase the total displacement of the launched object.

The test involved launching the object and measuring the initial height angle and the displacement of the object. The solid heavy base provides an easy to use and reliable setup. If the vertical velocity component is equal to 0 then it s the case of horizontal projectile motion. The vertical velocity changes by 9 8 m s each second of motion.

Place the cpo launcher near the edge of a student desk. Arrange the desk in a way such that the direction of launch will be clear for at least 4 meters. Launch steel balls at angles between 0 and 70 degrees and over distances up to 2 5 m. Put the timer in interval mode and connect the photogate to input a.

Use the vernier projectile launcher to investigate important concepts in two dimensional kinematics. Extra problems 1 a car dnves offa wharf at 15 m s if the wharf is 25 m above water calculate. On the other hand the horizontal acceleration is 0 m s s and the projectile continues with a constant horizontal velocity throughout its entire trajectory. Write down the equations of motion.

The vertical velocity component vy is equal to v sin α. Durable apparatus to study velocity acceleration and projectile motion. Velocity of the marble can range from 3 m s to 9 m s.
