| The Ballistic Pendulum | Determining the initial speed of a projectile | | | | | THE BALLISTIC PENDULUM ABSTRACT The experiment was carried out to determine the initial speed of a projectile: i) by means of a ballistic pendulum. ii) by measurements of the range and vertical distance of fall during its flight. The initial speed for the ballistic pendulum was found to be 5.0551±0.0008m/s and the initial speed for the pendulum was found to be 4.72±0.02 m/s. INTRODUCTION:

F40 BMA Tutorial 4 1. A man is driving at 120 km/h along a straight road and he looks to the side for 2.0 s‚ how far does he travel during this inattentive period? [66.7 m] 2. A horse canters away from its trainer in a straight line‚ moving 160 m away in 17.0 s. It then turns abruptly and gallops halfway back in 6.8 s. Calculate (a) its average speed and (b) its average velocity for the entire trip‚ using “away from the trainer” as the positive direction. [10.1 m/s; 3.36 m/s]

base gives the trebuchet a secure base to help with over rotation and other engineering problems that may occur. The counterweight falls and the force of gravity thrusts the projectile forwards. The throwing arm is used to connect the counterweight and sling‚ and is part of the thrust downwards.The sling holds the projectile and the pivot is there to prevent over-rotation. Trebuchets can be made from many things‚ and some parts can be made of different materials. Wood is most commonly used for small-scale

can thoroughly asses my non dominant arm tennis ball throw from my preparation phase to my execution phase of the throw. Just looking at the shoulder of my left arm which is a Ball and Socket synovial joint‚ which is a joint that allows for a large range of different movements. From the preparation phase to the execution phase‚ my left shoulder is abducted with slight protraction this is because my arm is away from my midline. This is happening due to my agonist muscle which is my deltoids which are

My reusable target data card is categorized by; projectile type‚ projectile grains‚ powder type‚ powder grains‚ case length and Minute of Angle achieved in three shot groups. The number 1 is for 100 yards‚ 2 is for 200 yards and 3 is for 300 yards with a line for Minute of Angle (M.O.A) measured. I have a non-reusable

force a piece of an object to move at greater than the speed of sound through that medium it will simply tear whatever is holding it together without transmitting force to the surrounding structure. this gives a kind of hole punch effect if the projectile is moving faster than the speed of sound in the target. the maximum known speed of sound is about 15km/s in diamond‚ given that a dreaddie shot moves at about 4000Km/s it is safe to assume that armor ain’t going to do shit. given the momentum behind

PHY 1103 Physics I RKMC - HCT Learning Outcome 1: Sub-outcome 1: Assign given basic units to their corresponding physical quantities. All engineers must use the same language in their communications‚ and one of these universal communication tools is the units of measurements. Physical quantities such as length‚ weight‚ time‚ speed‚ force‚ and mass are measured with standard units. Therefore the magnitude if a physical quantity is given by a number and standard unit of measurement

is to determine what projectile for a Ballista will travel the furthest‚ to do this two variables will be changed through the duration of the testing period. These variables are: the angle and the different materials the projectile is made of. The three different materials being used for the projectiles are a pencil‚ a bit of wood and a replica of an original Ballista bolt. The Results of this experiment is hypothesised that the replica Ballista bolt will have the most range of the three. Ballista

design. The trebuchet is sort of more like a massive slingshot. It is also one of the most efficient designs of catapult‚ in terms of transferring energy into the projectile and the accuracy of the projectile.

connect to the firing mechanism through wires‚ the typical Taser has a range limited to the length of the wires -- about 35 feet (10.6 meters). And while a Taser works well for taking down a single subject‚ it’s not easy to reload a fired Taser device -- something that may be necessary in crowd control situations. With that in mind‚ Taser introduced a new concept in ECD technology the Taser eXtended Range Electronic Projectile (XREP). The XREP looks like a high-tech shotgun shell. That’s not by accident
