Please help!! I need this asap! thank you so much!! <3
Compared to a ball thrown at 10 meters per second, which statement describes the change in kinetic energy of a ball of the same mass thrown at 20 meters per second?
1) The kinetic energy of the ball thrown at 20 meters per second is half (½×) the kinetic energy of the ball thrown at 10 meters per second.
2) The kinetic energy of the ball thrown at 20 meters per second is two times (2×) the kinetic energy of the ball thrown at 10 meters per second.
3) The kinetic energy of the ball thrown at 20 meters per second is the same as (=) the kinetic energy of the ball thrown at 10 meters per second.
4) The kinetic energy of the ball thrown at 20 meters per second is four times (4×) the kinetic energy of the ball thrown at 10 meters per second.
Answer:
Does a car's kinetic energy change more when the car speeds up from 10 to 15 m/s or from 15 to 20 m/s explain?
Answer and Explanation: The kinetic energy changes more if the car goes from 15 m/s to 20 m/s.

please help!! i need this asap <3
(the boxes have the same answer choices in both)
Answer:
going based off the graph, it looks like for the first one it's 50 and the second is 200.
