2. The motion of roller coasters depends upon the conversion of potential

Gnesinka [82]

Answer:

58,800 Joules

Explanation:

I used the formula for Potential energy which is PE = mgh

200 kg x 9.8 m/s^2 x 30 m = 58,800 J

At the very tops of the rollercoaster is maximum PE which is 58,800 J and 0 J of KE, but at the very bottom is maximum KE (kinetic energy) which is 58,800 Joules but 0 J of PE. This is because energy can not be destroyed ONLY converted

Viefleur [7K]

Answer:

1.65 m

Explanation:

Energy from spring, $E_{s}$ is given by

$E_{s}=0.5kx^{2}$ where k is spring constant and x is the compression distance

$E_{s}=0.5*51.1*0.129^{2}= 0.425178$

$E_{s}=0.425 J$

Kinetic energy, KE at the highest point is given by

$KE=0.5mv^{2}$ where m is mass and v is velocity

KE=0.5*0.0227*2.27= 0.058485 J

Potential energy, PE of spring is given by

PE=mgh where g is gravitational constant and h is maximum height reached by the mouse

PE=0.0227*9.81= 0.222687h

According to the principle of conservation of energy, the potential energy of the compressed spring is equal to the potential and kinetic energy of the mouse at the maximum high point.

$E_{s}=PE+KE$

0.425=0.222687h+0.058485

h=(0.425-0.058485)/ 0.222687=1.646671 m

h=1.65 m
