Calculating Final Velocity Try it
A roller coaster is traveling at 13 m/s when it approaches a hill that is 400 m long. Heading down the hill, it
accelerates at 4.0 m/s2. What is the final velocity of the roller coaster? Round your answer to the nearest whole
number
m/s

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation 2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!
