Given the position function
<em>s(t)</em> = 3 - cos(<em>t</em> )
differentiate once to get the velocity, and twice to get the acceleration:
<em>v(t)</em> = <em>s'(t)</em> = sin(<em>t </em>) → <em>v</em> (4.3 s) ≈ -0.92
<em>a(t)</em> = <em>s''(t)</em> = <em>v'(t)</em> = cos(<em>t </em>) → <em>a</em> (4.3 s) ≈ -0.40
The acceleration is negative, so the particle is slowing down.

Answer:
1920 ft^3
Step-by-step explanation:
Split it in 2.
14*8*10 and 10*10*8
14*10*8 = 1120
10*10*8 = 800
800 + 1120 = 1920
The answer is 4.5 because you are multiplying 1.5 times 3 = 4.5
