Additional Questions 3: Kinematics 1. A balloon is 30.0 m above the ground and is rising vertically with a uniform speed when a coin is dropped from it. If the coin reaches the ground in 4.00 s‚ what is the speed of the balloon? Solution:- Initial velocity of coin = speed of balloon‚ v. by using the equation [Answer: 12.1 ms–1] 2. A car and train moves together along two parallel paths at 25.0 ms–1. The car then undergoes a uniform

Go to http://phet.colorado.edu/simulations/sims.php?sim=Motion_in_2D and click on Run Now. 1) Once the simulation opens‚ click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. The vectors appear to have both direct and inverse relationships with each other. When I move the ball one direction‚ both of the vectors move the

Spoon River Anthology The Spoon River Anthology is a story of many different cultured people all dying in a small town known as Spoon River. This play was based upon free-verse‚ and gravestone epitaphs‚ where the dead actually told their own story. The mood of the play was very dark. The lighting for this play set the mood‚ timid yet bold in some moments. The Scenery was based around a large grave stone. I wish there would have been more props; it would have made the play a lot more interesting

spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity. This compression of Domino’s shares a very close

HOMEWORK PROBLEMS Chapter-4: MOTION IN TWO DIMENSIONS 1 A particle starts from the origin at t = 0 with a velocity of 6.0[pic] m/s and moves in the xy plane with a constant acceleration of (-2.0[pic] + 4.0[pic]) m/s2. At the instant the particle achieves its maximum positive x coordinate‚ how far is it from the origin? [pic] 2 At t = 0‚ a particle leaves the origin with a velocity of 5.0 m/s in the positive y direction. Its acceleration is given by [pic] = (3.0[pic] - 2.0[pic]) m/s2. At the
