AP Physics HW #1 Multiple Choice 1. A car travels 30 miles at an average speed of 60 miles per hour and then 30 miles at an average speed of 30 miles per hour. The average speed the car over the 60 miles is (A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Answer: B. Method: Vavg = Δx/Δt The average speed is the total distance traveled‚ divided by the total time. They give us all distances traveled is‚ so we just need to find the time. We find the time‚ by applying

Projectile Motion Purpose: An object in a projectile motion move horizontally with no acceleration and vertically with the gravitational acceleration at the same time. This experiment is to investigate projectile motion using experiments‚ equations and comparing the expected and experimental data. Procedure: Case I: Use formulas to find equation of horizontal Range (R) in a projectile motion. Rearrange equation for Rmax‚ and find the angle Adjust the launches angle to angle Launch

Lab - Section 001 CP1 Lab Report - Projectile Motion October 12‚ 2009 The purpose of Lab Assignment 1 was to analyze projectile motion. In doing so‚ we determined the initial velocity of the ball shot horizontally from the spring loaded projectile launcher. Also‚ we verified the angle at which the projection of the ball would produce a maximum range. Lastly‚ we predicted the range that a ball would travel at a certain angle‚ theta. Projectile motion is the motion of objects that are

bullet) is thrown‚ hurled or shot in the air‚ the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not‚ he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food. In today’s sports‚ balls follow projectile motion such as when a basketball player shoots the ball

Appendix 5 26 Appendix 6 28 Appendix 7 30 Appendix 8 31 Appendix 9 33 Appendix 10 35 Background Information Sport relies on three major physics concepts: force‚ acceleration and velocity; many of which involve elastic propulsion and/or projectile motion. Various types of sporting equipment are constructed with springs and elastics‚ in order to absorb a force or apply a force to another object. In the context of this investigation‚ the spring is utilised to propel an object. According to

Projectile Motion By Kaneisha Winch Aim: To investigate whether there is a relationship between the horizontal velocity and vertical velocity by using a 7.5 cm baseball in projectile motion. Hypothesis: There is no relationship between the horizontal and vertical velocity. No matter how fast the horizontal velocity‚ the vertical velocity will remain the same. This has no relation to the size or mass of the ball. Materials: • a baseball with a diameter of approx. 7.5 cm • a tape measurer • a surface

Down Range is a book by Dick Couch‚ a former Navy Seal. He tells about how he became a navy seal and his experiences. He also writes about other missions that he was not even in‚ including missions by the famous American sniper‚ Chris Kyle‚ who is the world’s most deadly sniper. The motive of a Navy Seal is to be the best gunman in the world‚ plus being stealthy‚ effective‚ professional‚ and lethal. Dick Couch did this and he was on the battlefield. Couch was in the Navy seals in the 1980’s

shots fired at 45° had a greater distance from the shots fired at 0° horizontally. This is because as the ball which is fired increases‚ the height increases. As the height increases‚ the time it takes for the ball to hit the ground increases and the range (distance) is greater. Conclusion: One source of error comes from when we shot the cannon from the ground at a
