Which best describes Lenny’s error?

Expert-Verified Answer In Step 3, he should have multiplied 6.25 J per m2/s2 by 2 instead of dividing it by 2 best describes Lenny’s error.

What is the kinetic energy of a 620.0 kg roller coaster?

Answer: The kinetic energy is equal to 25,110 J.

What is the kinetic energy of an object with a mass of 6.8 kg?

Expert-Verified Answer The kinetic energy of the object reported to two significant figures is: 85 Joules. Given the following data: Mass = 6.8 kg.

Are kinetic energy and mass proportional?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.

Which formula can be used to find velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

Which formula can be used to find velocity if kinetic energy?

Part

What is the formula for kinetic energy of a roller coaster?

Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2). Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.

What is the formula for potential energy of a roller coaster?

Part

What is the highest kinetic energy on a roller coaster?

When the roller coaster moves downwards, kinetic energy is generated. The maximum kinetic energy generated is when the roller coaster is at the bottom of the track. When it begins to go up, the kinetic energy converts to potential energy.

What is the kinetic energy of a 45 kg object moving at 13?

What is the kinetic energy of a 45 kg object moving at 13 m/sec? 3. Solving the equation gives a kinetic energy value of 3802.5 J. Note: The unit for energy is the same as for work: the Joule (J).

What is the kinetic energy of a 10 kg object moving at 5 ms?

The kinetic energy of the object is 125 J.

What is the kinetic energy of a body of mass 0.2 kg and momentum 25 kg ms?

= 1562.5 Joules. Thus the Kinetic Energy of the body is 1562.5 Joules.

What best describes Alana’s error?

Which best describes Alana’s error? Kinetic energy is not made; it is a result of energy transformation.

What is the best response that Shari’s friend could make?

she could agree with shari because the pendulum is at the same height and would have the same gravitational potential energy at both positions.

Which best describes step 4?

Which best describes Step 4? Elastic potential energy changes to gravitational potential energy.

Which best summarizes the concept related to the work energy theorem?

When work is positive, the environment does work on an object.
