5. During its launch phase‚ a space-rocket accelerates uniformly from rest to 160 m s−1 in 4.0 s‚ then travels with a constant speed of 160 m s−1 for the next 5.0s. a. Calculate the initial acceleration of the rocket. b. How far does the rocket travel in this 9s period? c. What is the final speed of the rocket in km h−1? d. What is the average speed of the rocket during the first 4.0s? e. What is the average speed of the rocket during the 9.0s motion? 6. A diver

compressed. Another example is when you’re in a rocket either you’re in space or trying to escape the atmosphere there’s nothing to push up that lets you accelerate. How would you accelerate? you would accelerate by keeping stuff that would push off the rocket like your fuel tank when you allow the proper chemical reaction or combustion to take place what it does‚ it expels gases at ultra high velocities out the back of your rockets the rocket then accelerates and a equal and

1. When someone says they are going to us a sample to draw an inference about a population‚ it means that rather than survey the entire population‚ they’ll survey a smaller group and apply the results to a larger group. For example‚ if you take a neighborhood in a town with 100 homes and survey approximately 80% of the households and 76% of those families own multiple televisions you may infer that the majority of the 100 home neighborhood also own multiple televisions. A simple random sample

Details about Gunpowder Gunpowder is one of the revolutionary Chinese inventions that has greatly changed the modern world. Gunpowder is mainly used to fuel military weapons‚ such as bombs and guns. Gunpowder was first introduced during the Song and Mongol periods where it was developed and used by the Chinese to overthrow the Mongols. After gunpowder’s introduction‚ alchemists recorded the formula for gunpowder and developed the first weapon that used gunpowder‚ which was the flamethrower. “In 850

The Space Race and the Cold War “That’s One Small Step for Man‚ One Giant Leap for Mankind”. These words were heard worldwide when astronaut Neil Armstrong first stepped foot on the moon. When the Apollo 11 mission launched on July 16‚ 1969‚ carrying astronauts Neil Armstrong‚ Michael Collins‚ and Buzz Aldrin‚ the world was immersed in the middle of the Cold War between the United States and the Soviet Union which had in essence split the globe into two radically different ideologies that

Physics HSC Notes Space 1. Earth has a gravitational field that exerts a force on objects both on it and around it. K1 Define weight as the force on an object due to a gravitational field. Mass is the amount of matter within an object‚ measured in kg Weight is the force of gravity acting on an object’s mass measured in newtons (N). Weight is a force thus a vector quantity. K2 Explain that a change in gravitational potential

then the rocket ride. After driving for what seemed like days‚ we finally arrived. I remember thinking to myself how big the park was. I felt like a small fish in the ocean. Everything looked so big and so scary. First‚ we headed straight to the roller coaster. As we got on the coaster car and began up the steep incline‚ I remember thinking I was high enough to touch the clouds. This roller coaster had to be the biggest in the world! After the roller coaster‚ our next stop was the rocket ride. The
