Answer:
h = 27.17 m
Explanation:
First, we will calculate the total mechanical energy of the system at the bottom point of the third loop:
Mechanical Energy = Kinetic Energy + Potential Energy
where,
E = Total Mechanical Energy = ?
m = mass of the roller coaster = 1200 kg
v = velocity of the roller coaster = 22 m/s
g = acceleration due to gravity = 9.81 m/s²
h = height of roller coaster = 2.5 m
Therefore,
Now, the total mechanical energy at the top position of the first hill must also be the same:
where,
v = 0 m/s
h = ?
Therefore,
<u>h = 27.17 m</u>
The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due its motion. It is given by
where
m is the mass of the object
v is its speed
For the car in this problem, we have:
m = 1000 kg is its mass
v = 30 m/s is its speed
Substituting into the equation, we find the kinetic energy of the car:
