-7x^2 - 6x^2 + 3x + 5x - 5 + 2
-13x^2 + 8x - 3
I don't understand what you mean but this might be the answer
The kinetic energy transfers from the moving ball to the non-moving ball.
12/2+4-2*3
According to the order of operations, evaluate division and multiplication first.
6+4-6
Then add and subtract from left to right
10-6
4
Final answer: A
Use the equation of motion under gravity:-
s = 16t^2 where s is the distance and t = time
2063 = 16t^2
t^2 = 2063 / 16 = 128.94 s
t = sqrt 128.94 = 11. 4 seconds to the nearest tenth of a second
