C) Find the kinetic of a ball of mass 200 grams moving at a speed of 20 m/s. [Ans; 20 )]
Solution,
Mass (m): 200 g
velocity (v) = 20 m/s
kinetic Energy (k. E)= ?
We know,
According to the formula,

the answer is k.E =0.5

Explanation:

i only think about it and i answer it

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
