Physics 221 Summer 2012 HOMEWORK #3 Due Monday July 2‚ 2012 1 James Bond (90 kg)‚ outfitted with perfectly matching skis and skiware‚ is at the top of a steep slope that a secret spy like him can easily handle. He lets himself go from rest and smoothly slides down the h = 15 m high hill. A big parking lot lies at the bottom of the hill. Since the parking area has been cleared of snow‚ the friction between the ground and the skis brings our hero to a halt at point D‚ located at a distance

------------------------------------------------- Terminology Many different terms are commonly used to describe vehicle collisions. The World Health Organization use the term road traffic injury‚[1] while the U.S. Census Bureau uses the term motor vehicle accidents (MVA)[2] and Transport Canada uses the term "motor vehicle traffic collision" (MVTC).[3] Other terms that are commonly used include auto accident‚ car accident‚ car crash‚ car smash‚ car wreck‚ motor vehicle collision (MVC)‚ personal

Calculus is a type of math that is applicable to various parts of our life. We can use calculus to calculate the maximum production of a company‚ to predict the speed of global warming spreading to the world‚ and etc. Calculus is not limited to only mathematics in class‚ but many aspects of the world. We chose physics as our topic of calculus application in real world because we believe that physics phenomenon is very common in our life. Physics is involved in many aspects of our life‚ such as driving

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total

1) Annual energy consumption in the United States (Q24; Giancoli Chap 26) The total annual energy consumption in the United States is about 8 10 J. 19 How much mass would have to be converted to energy to fuel this need? 2) The nearest star to Earth (Q49; Giancoli Chap 26) The nearest star to Earth is Proxima Centauri‚ 4.3 light-years away. (a) At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 4.0 years‚ as measured by travellers on the spacecraft?

SPH4U0 2-D COLLISIONS LAB PURPOSE To determine if momentum and kinetic energy are conserved during elastic and inelastic collisions. PROCEDURE AND CALCULATIONS 1. Run both the elastic and inelastic collision simulations and record the data as instructed by the teacher (you will do an import). You will need to base your calculations on the data before and after the collision. Do not use data in the middle because it is not clear exactly when the collision occurs. The software measures time
