Answer:
D. 4x as much
Explanation:
The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.
You can also prove this mathematically. The formula for kinetic energy is
[tex]\frac{1}{2}mv^2[/tex]
The question says: constant mass so we can ignore that for now.
(1/2) * 10^2 is (1/2) * 100 = 50
for the 20m/s ball it would be
(1/2) * 20^2 = 400 * 1/2 = 200
Once again, you see that it is 4x
Answer:
It is weird that you put this the computer and tech. But it's (D. 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. !!
Explanation:
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.
Explanation:
lmk if it's right or wrong </3
