The 20 kg ball
They hit the ground at the same time
There is not enough information

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

less than one you can't create energy
