Answer:
571,725 J
Step-by-step explanation:
KE = 1/2mv²
KE = 1/2(1050 kg)(33 m/s)² = 571,725 J
Slope=7/2=3.5

Sum of interior angles in a triangle = 180
2x - 1 + 11x + 3 + 5(x - 4) = 180
13x + 2 + 5x - 20 = 180
18x - 18 = 180
18x = 198
x = 11
6900000 + (6900000 * x) = 7400000
This equation is telling us 6900000 plus 6900000 times a specific percent will get us 7400000, which is what we want.
6900000 + (6900000 * x) = 7400000
6900000 + 6900000x = 7400000
Subtract 6900000 from both sides.
6900000x = 500000
Divide both sides by 6900000
x = 0.0724637681, or .07 when rounded to the nearest tenth.
We can convert .07 to a percentage by moving the decimal point two places to the right.
.07 = 7%
