leaps at an angle of 35° with respect to the horizontal. What is the minimum initial speed that would allow the athlete to clear the gap? Neglect air resistance. SOLUTION 1. DEFINE Given: ∆x = 6.0 m q = 35° g = 9.81 m/s vi = ? Unknown: 2. PLAN Diagram: v θ = 35° ∆x = 6.00 m Choose the equation(s) or situation: The horizontal component of the athlete’s velocity‚ vx ‚ is equal to the initial speed multiplied by the cosine of the angle‚ q‚ which is equal to the magnitude of the horizontal

Michigan entrepreneur Justin Eric Sutton brings us into the era of clean hydrogen energy and solar energy‚ by producing a remarkable high speed MAGLEV railway which is being sold throughout the USA for deployment on Elevated Superhighway Rails‚ it speeds travelers between metro areas at up to 250+ MPH‚ in this remarkable vision of the not so distant future! Not only would it revolutionize energy AND transportation‚ it is both feasible and deployable TODAY. All that remains is funding and agreements

The crate will not hit the Camaro‚ but will crash a distance beyond it determined by the height and speed of the plane. 4. The crate will hit the front part of the car. 003 10.0 points A ball is thrown horizontally at speed v0 from the top edge of a cliff of height h. Neglecting air resistance‚ which statement is wrong? 1. The time it takes for the ball to hit the ground does not depend in any way on v0

rate of change of velocity. Acceleration can be caused by a change in speed or direction or both. For example‚ a skater who goes from a standstill to full speed quicker than another skater has greater acceleration. Likewise‚ a skater who can stop quicker than another skater has greater deceleration--assuming both skaters were traveling at the same speed. Another example of acceleration is a skater who travels at a constant speed around the ice rink. In the corners‚ when this skater is changing direction

blue and green arrows (also called vectors) as you drag the ball around. 1. The green line points in the direction that the ball is going to go 2. The blue line changes the direction it points. 3. The blue line also changes size depending on the speed 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? The green line represents velocity because it points in the direction. The blue line is acceleration because as the ball is no longer accelerating

notebooks. Others include a glider and his helicopter-like aerial screw‚ which we’ll talk about in a few pages. parachute-The speed at which a body falls depends on two factors: the force of the gravity pulling it downward and the resistance of the atmosphere through which it is falling. If there were no atmosphere‚ a falling body would simply accelerate to higher and higher speeds until it hit a surface‚ but air tends to slow it down until it reaches its so-called terminal velocity.

Officer Speedy then took the time to pursue the black sports car through downtown Saint Leo. Their speeds were in excess of 100 miles per hour around midnight when many people were out enjoying the night life. These people included pedestrians and those going to their vehicles to either head home or to other businesses in the area. Officer Speedy lost
