EXPERIMENT 4: Projectile Motion LAB SECTION: Section 1 Objective: The objective of this lab is to study vector addition by three different methods (component method, graphical method and using a force table.) Theory: Vectors are quantities that have both magnitude and direction and follow specific rules of combination. Two of these rules are the commutative and associative laws of addition. The graphical method will be used to verify this rule. Equipment /Apparatus: 1. Beck Ballistic Pendulum (spring gun) 2. Wooden block 3. Metre rule 4. Mahjong Paper 5. Carbon Paper 6. Inclinometer

7. Height gauge Procedure: 1. Number inscribed on the firing mechanism of the pendulum was recorded. 2. The ballistic pendulum was placed on a platform with pendulum arm in the up position. The height from the floor to the bottom of the ball was measured as follows: The height gauge was used to measure the distance from the table top to the bottom of the ball and the meter stick was used to measure the height of the table above the floor. Two distances were added together to get the total height h. 3. The amount of time the ball will be in the air when fired horizontally was calculated. Recall that if two balls are released at the same time, one falling vertically and the other projected horizontally, both will hit the ground at the same time. 4. Video instructions on firing the ballistic pendulum can be found on your computer. The spring gun was fired from the 1st detent, the gun was held firmly in position. Point where the ball lands was noted and a target composed of carbon and white sheets of paper at that spot. The spring gun was fired for 3 times. 5. For each trial, total distance of the ball travelled horizontally were measured. ( Total distance from the pendulum in the uncocked position to the point of impact on the floor was added). The average horizontal distance of all the trials were recorded. From this value and the time calculated in step 3, the speed at which the ball leaves the gun was calculated. 6. The front feet of the spring gun was placed on the incline block and inclinometer was used to measure the angle of inclination. The distance from the bottom of the ball to the floor was measured 7. Equation 4&5 and the quadratic equation were used to calculate the horizontal range of the ball when fired at the above angle and height in step 6.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
