GS104 Lab Report Experiment # 2 Data Collection David Case: January 23‚ 2015 Experiment #2 Data Collection Objectives: Exercise 1: Formulating a Hypothesis about pitching speed. To form a hypothesis for the pitching velocity of a ball. Use a spreadsheet and math to calculate the actual velocity and determine the accuracy of the hypothesis. I will also roll a large ball to measure its velocity and graph its horizontal motion. Materials: Volley

PROJECTILE MOTION PRACTICE QUESTIONS (WITH ANSWERS) * challenge questions Q1. A golfer practising on a range with an elevated tee 4.9 m above the fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20 m s–1. (Assume the acceleration due to gravity is 9.80 m s–2‚ and the effects of air resistance may be ignored unless otherwise stated.) a b c d e How long after the ball leaves the club will it land on the fairway? What horizontal distance will the ball travel

II Uniform Circular Motion A. Nomenclature 1. Speed – magnitude of an objects rate of motion (no direction‚ scalar quantity) 2. Velocity – speed and direction of an objects motion (vector‚ mag & direction) 3. If a car’s speed is constant but direction is changing‚ velocity is changing. 4. 2 ways to change velocity (change speed or change direction). 5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed

Section 2C 5. A car enters the freeway with a speed of 6.4 m/s and accelerates uniformly for 3.2 km in 3.5 min. How fast is the car moving after this time? 3.5 min = 210 s. Average speed = 3 200/210 = 15.238 m/s = ½ (v + vo). vo = 6.4 m/s. Solving for v‚ v = 2 × 15.238 – 6.4 = 24.076 m/s. 2D 1. A car with an initial speed of 23.7 km/h accelerates at a uniform rate of 0.92m/s2 for 3.6 s. Find the final speed and the displacement of the car during this time. Vf= Vi + at= 9.92m/s D x= Vot+

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]

7 Holt Physics Chapter 7: Rotational Motion and the Law of Gravity I. Section 7-1: Measuring Rotational Motion A. When something spins it undergoes “rotational motion”. When something spins around a single point it is called “circular motion”. B. We measure how fast something spins not in m/s (different points on the object are spinning at different velocities) but by measuring the angle described in a given time period. C. Angles can be measured in radians
