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

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

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

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

LivePhoto Physics Activity 12 Name: __________________________ Date: __________________10/22/14_________ Projectile Motion Vectors There are multiple ways to represent an object’s motion. If the motion is two-dimensional and lies in a plane‚ some representations include: (1) recording x and y coordinates of the object at different times in a data table; (2) displaying the object’s x and y locations at regular time intervals on a diagram; (3) drawing vectors showing displacement‚ velocity

Chris Crouse‚ Juan Agosto‚ Bianca Butler‚ Hunter Zaun Feb. 12‚ 2013 Mrs. Rarig Physics Projectile Range Versus Angle Intro: First off‚ what projectile motion is motion in two dimensions in both X & Y directions. The only force on the projectile is gravity. With gravity being a presence and a factor in our everyday lives and in this experiment‚ gravity will push down on the projectile forcing it back down to the ground. For example if someone shot a cannon straight and there was no gravity

Lab #1: Projectile Motion Purpose: To determine experimentally the initial and final velocities of an air powered projectile. Hypothesis: If the angle of the rocket is launched at 45 degrees than the distance and velocity will maximize. Materials: Rocket launching platform Rocket launcher Rocket body Air pump Safety goggles Rubber washer Nose cone 40‚ 45‚ 50‚ 55 and 60 angle wooden blocks Measuring wheel Procedure: 1. The rocket was assembled by the rocket launcher

The equipment used in this experiment was a projectile launcher (ME-6800)‚ a drop shoot accessory (ME-9859)‚ one photogate (ME-9204A)‚ white paper‚ carbon paper‚ two time-of-flight timing pad (ME-6810)‚ two balls (ball 1 and ball 2)‚ and an interface computer. Ball 1 is dropped from rest (free fall)‚ and ball 2 is simultaneously projected horizontally (projectile motion); successive positions of these two balls are separated by equal time intervals. At

Paul Abidogun‚ Dexter Aguado Block ½ September 22‚ 2014 Ballistic Pendulum Lab Objective: Determine the velocity of the projectile as it reaches the pendulum. Hypothesis: Firstly‚ we guess that the outcome of the velocity of the projectile is 6.3 meters per second [left].The formulas we use to find the final velocity of the projectile are Trigonometry‚ Kinetic and Potential Energy‚ and Momentum. Mass of the pendulum = 80.0g Mass of the ball = 7.64g Length of the string = 21cm

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
