KE = 1/2mV2

KE = 1/2(30 kg)( 5m/s)2

= 750 joules of kinetic energy

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.

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.

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.
