Question

HURRY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

One object has a speed of 1 mph and another object has a speed of 3 mph. If the masses are the same, which of the following is true about their kinetic energy?

Question 7 options:

Their speeds are the same.

the object with the greater speed has greater kinetic energy


the object greater speed has the lower kinetic energy


the object with the smaller mass has the greater kinetic energy

Answer 1

The object with the greater speed has greater kinetic energy

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

Kinetic energy is the energy due to the motion of an object.

Mathematically, K.E =
`(1)/(2)mv^(2)`

where m = mass

v = velocity

Therefore, an object whose velocity is more will have more kinetic energy.

Thus, we can conclude that out of the given options, the object with the greater speed has greater kinetic energy is true about their kinetic energy.
