You are riding on a roller coaster that starts from rest at a height of 25.0 m and moves down a frictionless track to a height of 3.00 m. how fast are you moving when you arrive at the 3.00-m height? you are riding on a roller coaster that starts from rest at a height of 25.0 m and moves down a frictionless track to a height of 3.00 m. how fast are you moving when you arrive at the 3.00-m height? 20.8 m/s 14.7 m/s 22.1 m/s 23.4 m/s submitrequest answer part b you are riding on a roller coaster that starts from rest at a height of 25.0 m and moves along a frictionless track. how fast are you moving when you reach the top of the loop, at point b? you are riding on a roller coaster that starts from rest at a height of 25.0 m and moves along a frictionless track. how fast are you moving when you reach the top of the loop, at point b? 20.3 m/s 13.3 m/s 16.0 m/s 26.9 m/s submitrequest answer part c you are riding on a roller coaster that starts from rest at a height of 25.0 m and moves along a frictionless track. however, after a bad storm some leaves settled on part of the track causing a 9.4-m length of the track to exert a frictional force of 625 n on the car. to safely make it around the loop, the 50-kg car must have a minimum speed of 7.7 m/s at the top of the loop (point b). how fast should the car be moving initially at point a to ensure that it reaches the top of the loop with the minimum required speed?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
