I need help with science I suck at it I'm at unit 5 lesson 4 Quick check help me pls !!!!!!!!!!!!!!!!!!!!
I have no idea what unit 5 lesson 4 contains.
Post your question and how you think it should solved and we can help.
ok so this is the first one Two objects with equal masses are in motion. Which object will have more kinetic energy? the answers are
the object with the greater acceleration
the object with the greater density
the object with the greater speed
the object with the greater volume
this is 2 A large truck and a small car are found to have the same kinetic energy. How is this possible?
The car is at a higher point on a hill.
The car is moving faster.
The car is accelerating more.
The car and truck have the same speed.
Hey there! Don't worry, I'm here to make science a little more fun and less sucky for you. What's the question on your Unit 5 Lesson 4 Quick Check? Fire away, and together we'll tackle it with a dash of humor!
Of course! I'd be happy to help you with your science quick check. However, I'll need a bit more information about what specifically you're having trouble with in Unit 5 Lesson 4. Can you provide me with the specific question or concept you need assistance with?
this is 3 Which object has the greatest kinetic energy?(1 point)
a baseball with a mass of 0.5 kg moving at 30 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 car with a mass of 1,000 kg moving at 3 m/s
this is 4 Use the image to answer the question.
An illustration shows a person running after a rabbit. The person weighs 60 kilograms, and the rabbit weighs 4 kilograms. The speed of both is 5 meters per second.
A wildlife keeper chases a rabbit that is trying to escape. In which situation would you be able to identify the object with the greater kinetic energy? Assume that only the changes described happen and that all other factors remain the same.
(1 point)
The wildlife keeper increases speed and catches the rabbit.
The rabbit increases speed and manages to escape.
Instead of the wildlife keeper, a second rabbit chases the first rabbit.
Instead of the rabbit, a pig with a greater mass tries to escape.
this is 5A 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?(1 point)
His kinetic energy would remain the same for the whole fall as long as he lost no mass
His kinetic energy was positive at first, but it decreased to zero when he stopped accelerating.
His kinetic energy increased for a while, then it became constant.
His kinetic energy increased quickly at first, then it increased at a constant rate.
