Two objects with equal masses are in motion. Which object will have more kinetic energy? (1 point)
the object with the greater volume
the object with the greater velocity
the object with the greater density
the object with the greater acceleration***
A large truck and a small car are found to have the same kinetic energy. How is this possible?(1 point)
The car would have to be at a higher point on a hill.
The car must be moving with a greater velocity.
The car and truck must have the same velocity.***
The car would have to be accelerating more.
Which object has the greatest kinetic energy?(1 point)
a car with a mass of 1,000 kg moving at 3 m/s
a car with a mass of 1,000 kg moving at 30 m/s
a person with a mass of 70 kg walking at 3 m/s***
a baseball with a mass of 0.5 kg moving at 30 m/s
A wildlife keeper chases a rabbit that is trying to escape. It is possible to identify which object has the greater kinetic energy. In which situation would you also be able to identify with certainty the object with the greater kinetic energy? Assume that only the changes described happen and all other factors remain the same. (1 point)
The wildlife keeper increases her speed and catches the rabbit.
Instead of the wildlife keeper, a small dog chases the rabbit.
The rabbit increases its speed and manages to escape.***
Instead of the rabbit, a pig with a greater mass tries to escape.
A skydiver jumps out of a plane and begins to accelerate. His speed increases to 20 m/s, then 30 m/s, with air resistance increasing the entire time. His acceleration keeps decreasing until he reaches a constant speed of 50 m/s. What happened to his kinetic energy during this time?(1 point)
His kinetic energy increased for a while, then it became constant.
His kinetic energy would remain the same for the whole fall as long as he lost no mass.
His kinetic energy increased quickly at first, then it increased at a constant rate.
His kinetic energy was positive at first, but it decreased to zero when he stopped accelerating.***

1:object with greater velocity
2:car must be moving with a greater velocity
3:a car with a mass of 1,000 kg moving at 30 m/s
4:The wildlife keeper increases her speed and catches the rabbit.
5:His kinetic energy increased for a while, then it became constant.
these are the correct answers
2. The car is moving faster, A
3. A car with a mass of 1,000 kg moving at 30 m/s, D
4. The wildlife keeper increases speed and catches the rabbit, C
5. His kinetic energy increased for a while, then it became constant, C
100% correct, I promise
1: the object with greater speed
2:The car is moving faster
3:a car with a mass of 1,000 Kg moving at 30 m/s
4: the Wildlife Keeper increases speed and catches the Rabbit
5:His kinetic energy increased for a while, then it became constant.
( some of the questions will get reworded so yeah )
( maybe also get one wrong so they think your not cheating Idk xd)
is 100% correct! thanks
