Design a roller coaster with 1 loop and 1 hill following the lift hill. You will need to have several control points on your roller coaster
0) The top of the lift hill.
A = 9.8 m/s^2, v = 0 m/s, H selected
1) At the transition, set the radius (R1) so the acceleration is less than 40 m/s^2
2) At the mid-point of of the loop, set the radius (R2) and height (H2) so 0 <= a <= 40 m/s^2
3) At the top-point of of the loop, set the radius (R3) and height (H3) so 0 <= a <= 40 m/s^2
4) At the top of the hill, set the radius (which is NOT the same as the height) so a <= 0 <= 40 m/s^2

As , plants meet their needs for making food from air, soil, water, and the sun's energy in a process called there are plants called grow high in trees without here are words to put in the blanks. 1.) producers 2.) consumers 3.) chloroplasts 4.) epiphytes

Aman throws a football straight into the air. as it rises, it slows down. which type of energy is the football gaining?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
