KE = 1/2*m*v^2
velocity must be greater OR mass must be greater OR both.
A large truck and a small car are found to have the same kinetic energy. How is this possible?
The Answer is The car must be moving with a greater velocity.
Please correct me if i'm wrong

Don't trust cali i got 1/5
do you know the right answers?
ok never mind i did it my self and got 4/5 but now i have the right answer here they are:)
B. the object with the greater speed
C. The car is moving faster.
A. a car with a mass of 1,000 kg moving at 30 m/s
B. The wildlife keeper increases speed and catches the rabbit.
B. His kinetic energy increased for a while, then it became constant.
Don't ask me why there are so many B's but hopes this help:)

and thanks "supar girl" with the heads up:)
thanks carson 100% 🙏

1. You are told 3 things...1. That there are two object with equal masses. 2 Both objects are in motion. 3. One object has a greater kinetic energy that the other. How is this possible:
One object has a greater speed than the other object.
2. 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?
The truck has more kinetic energy because it has a greater mass.
3.Which object has the greatest kinetic energy?
A blue car with a mass of 500 kg moving at 30m/s
4. Use the image to answer the question. A wildlife keeper is trying to catch an escaping rabbit. Who has the greater kinetic energy, the rabbit, or the wildlife keeper?
The wildlife keeper because they have a greater mass
5. A skydiver jumps out of a plane and begins to accelerate. His speed increases to 20 m/s then 30 m/s. His acceleration slows until he reaches a constant speed of 50 m/s. Which statement correctly describes his kinetic energy during this time.
His kinetic energy increased while his speed increases, then it became constant.
One object has a greater speed than the other object.
