To have a weight of 2.21N., the ball's mass is (2.21/9.8) = .226kg.
<span>a) d = 1/2 (vt), = 1/2 (18 x .17), = 1.53m. </span>
<span>b) Acceleration of the ball = (v/t), = 18/.17, = 105.88m/sec^2. </span>
<span>f = (ma), = .226 x 105.88, = 23.92N. </span>
X + 2y = 10 . . . (1)
6y = -3x + 30 . . . (2)
From (2), 3x + 6y = 30
3(x + 2y = 10)
3 x (1)
Since, the second equation is a multiple of the first equation, the system will have an infinitely number of solutions.
Answer:
D. 4(3x-5) = 52
Step-by-step explanation:
52 is equal the sum of one side multiplied by 4
So
4(3x-5) = 52
Is the right answer
