A model rocket is fired vertically from an elevated launch pad at an initial height of 4 feet at an initial velocity of 350 feet per second. The gravitational force of Earth is pulling the rocket down at a rate of 16 feet per second per second. The formula for‚ s(t)‚ for the function that models the height of the water balloon at time t‚ in seconds‚ is s(t)= -16t2 + 350t + 4. We can determine how long it takes for the rocket to land from the graph where the function intercepts the x-axis because

issues the truth lies only within our heritage‚ our communities and within ourselves. We as human beings have the benefit of math and science to prove theories and explain just how something may or may not be accurate. As we learned from the "Red Balloon" video‚ things we believe to be the absolute truth may very well not be another person’s actuality. It is all dependent on what we have been taught by our families and the surroundings in our communities. Then all that is dependent on what we ourselves

Introduction A water bottle rocket is essentially that; a bottle modified in the image of a rocket then filled with a select amount of water that is pressurised and launched into the air due to the forces pushing the rocket upwards from the launcher. When the completed water bottle rocket is sitting on the launcher‚ the force of the surface of the launcher pushes the rocket up whilst gravity drags it down. As the fluid inside the rocket is pressurized‚ the forces become unbalanced

Before baseline 11-10 launches‚ the distance rocket traveled 6.73m and weighed 1.12 grams and the seconds rocket went .92 seconds and weighed .95 grams. By adding some cardstock for fins and taking off my clay and replacing it with tape it went quite a bit further and it went quite a bit faster‚ the weight was .93 grams. With the weight taken off‚ the rocket went 1.796 m farther. For the baseline launches‚ the distance average was 7.465m and .91 seconds and for the height the average was 2

A rocket is a machine that develops thrust by the rapid expulsion of matter. The major components of a chemical rocket assembly are a rocket motor or engine‚ propellant consisting of fuel and an oxidizer‚ a frame to hold the components‚ control systems and a cargo such as a satellite. A rocket differs from other engines in that it carries its fuel and oxidizer internally‚ therefore it will burn in the vacuum of space as well as within the Earth’s atmosphere. The cargo is commonly referred to as the
