You are told 3 things...1. That there are two objects with equal masses. 2. Both objects are in motion. 3. One object has a greater kinetic energy than the other. How is this possible? (1 point)
One object has a greater density then the other object.
One object has a greater speed than the other object.
One object is blue and one object is red.
One object has a greater volume than the other object.
One object has a greater speed than the other object.
you sure
Yes, I am certain. Kinetic energy is calculated using the equation KE = 1/2 * m * v^2, where m is the mass of the object and v is its speed. Since both objects have equal masses but are moving at different speeds, one object could have a greater kinetic energy than the other.
A large truck and a small car are moving at the same speed, traveling up and down hills, and over bumpy roads. Which one has more kinetic energy?(1 point)
The truck has less kinetic energy because it has greater mass.
The car and truck have the same kinetic energy.
The truck has more kinetic energy because it has a greater mass.
he car has more kinetic energy because it moves fast down hills.
The truck and car have the same kinetic energy.
are you sure
I apologize for the oversight. The correct answer is:
The truck has more kinetic energy because it has a greater mass.
Which object has the greatest kinetic energy?(1 point)
a red car mass of 500 kg moving at 3 m/s
a blue car with a mass of 500 kg moving at 30 m/s a
a yellow car with a mass of 500 kg moving at 12 m/s
a green car with a mass of 500kg moving at 21 m/s
