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>
Answer is 7/12 I know it is because, well I just know it is
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Among the choices provided the answer should be letter C. Below is the solution:
top
<span>pi r^2 or pi * 400 </span>
<span>sides </span>
<span>2 pi r * 60 </span>
<span>40 * 60 pi </span>
<span>2400pi </span>
<span>so add the top and side we get p*400 + p*2400 = 2800 pi ft^2</span>
