PLZ WHOS RIGHT???

Katelyn is right

Step-by-step explanation:

Her doubling of the speed of the watermelon will make a bigger increase in the kinetic energy. The kinetic energy of Katelyn's watermelon was 100 Joules at 10 m/s and 400 Joules at 20 m/sec. The kinetic energy of Robkins's 2 kg watermelon was 100 Joules and the kinetic energy of his 4kg watermelon was 200 Joules.

The kinetic energy of Katelyn's watermelon increased by 300 Joules (400 Joules - 100 Joules). The kinetic energy of Robin's watermelons increased by 100 Joules (2200 Joules - 100 Joules)

I found it on the internet

Hope that helps dude

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
