Vertical Marble Launcher

Marbles can be launched from five different speeds at any angle between 0 and 90.

Vertical marble launcher.

Three vectors v vx and vy form a right triangle. Attach one photogate to the marble launcher so that the marble breaks the light beam as it comes out of the barrel. Easy to read protractor allows for precise measurements and calculations. B how far from the table will it hit the floor.

If additionally α 90 then it s the case of free fall. The vertical velocity changes by 9 8 m s each second of motion. 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. Velocity of the marble can range from 3 m s to 9 m s.

If the vertical velocity component is equal to 0 then it s the case of horizontal projectile motion. Launch steel balls at angles between 0 and 70 degrees and over distances up to 2 5 m. Arrange the desk in a way such that the direction of launch will be clear for at least 4 meters. Projectiles are objects upon which the only force is gravity.

Write down the equations of motion. B the horizontal distance. The solid heavy base provides an easy to use and reliable setup. For this experiment you will use angles from 0 to 80 degrees.

The vertical velocity component vy is equal to v sin α. Place the cpo launcher near the edge of a student desk. Durable apparatus to study velocity acceleration and projectile motion. Put the timer in interval mode and connect the photogate to input a.

A the time of flight assume down is positive. Extra problems 1 a car dnves offa wharf at 15 m s if the wharf is 25 m above water calculate. The launcher can launch at angles from 0 horizontal to 90 degrees vertical. Use the vernier projectile launcher to investigate important concepts in two dimensional kinematics.

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. 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. Gravity being a vertical force causes a vertical acceleration.
