A 45.0 kg skater is skating down a hill on roller blades at a speed of 10.0 ms. What is the kinetic energy of the skater?
The kinetic energy of the skater is 2,250 Joules. This is calculated using the formula KE = 0.5 * mass * velocity^2, where mass = 45.0 kg and velocity = 10.0 m/s.
A 45.0 kg is skating down hill on roller blades at a speed of 10.0 ms. what is the kinetic energy of the skater?
The kinetic energy of the skater can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values, KE = 0.5 * 45 kg * (10 m/s)^2 = 2250 J. Therefore, the kinetic energy of the skater is 2250 Joules.
Can kinetic energy turn in to potential energy?
Yes, kinetic energy can be transformed into potential energy, and vice versa. For example, when a roller coaster reaches the top of a hill, its kinetic energy (motion) is converted into potential energy (height). Conversely, when the roller coaster descends the hill, the potential energy is converted back into kinetic energy.
What is an example of potiential energy to kinetic energy?
An example of potential energy transforming into kinetic energy is when a roller coaster reaches the top of a hill where it has high potential energy due to its height. As the roller coaster descends the hill, the potential energy converts into kinetic energy as it gains speed.
How is energy transferred from potential to kinetic on a roller coaster?
Energy is transferred from potential to kinetic on a roller coaster as the coaster descends from a higher elevation to a lower elevation. As the coaster moves downwards, gravitational potential energy is converted into kinetic energy. This energy transfer allows the coaster to gain speed and momentum.
What is the kinetic energy of a 45.0 kg skater who is skating down a hill on roller blades at a speed of 10.0 m per s?
kinetic_energy = ½mv² = ½ × 45 kg × (10 m/s)² = 2250 Joules.

When does a roller coaster increase kinetic energy?
A roller coaster increases kinetic energy when it is going downhill, as gravity is pulling it down and accelerating it. The potential energy is converted into kinetic energy as the roller coaster gains speed.
Can you use roller blades for figure skating?
If you are crazy enough to try, I don't see why not :)
Where is the kinetic energy the highest on a roller coaster?
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
Does carousel roller skating rink have roller blades?
If you are talking about the one in Massachusetts, in the Whitman area then yes. They are black and orange. Just saying.
In energy transformations when a roller coaster is at the top of the hill the kinetic energy is?
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
What energy is in a roller coaster?
Potential energy is used when going up hill on a roller coaster. When it starts gong down the potential energy is converted to kinetic energy.
What is an example kinetic energy?

Would a corkscrew on a roller coaster be potential energy or kinetic?
A corkscrew on a roller coaster would have kinetic energy as it moves through the track, turning potential energy (stored energy due to its height) into kinetic energy (energy of motion).
