The velocity of the rollercoaster going down the hill is equal to 5.270 m/s.
Given the following data:
- Mass of rollercoaster = 1,800 kilograms.
- Kinetic energy =25,000 Joules.
To calculate the velocity of the rollercoaster going down the hill:
Formula for kinetic energy.
Mathematically, kinetic energy is calculated by using the formula;
[tex]K.E = \frac{1}{2} MV^2[/tex]
Where:
- K.E is the kinetic energy.
- M is the mass of an object.
- V is the velocity of an object.
Making V the subject of formula, we have:
[tex]V =\sqrt{\frac{2K.E}{M} }[/tex]
Substituting the given parameters into the formula, we have;
[tex]V =\sqrt{\frac{2\times 25000}{1800} }\\\\V=\sqrt{27.7778}[/tex]
Velocity, V = 5.270 m/s
