hope this helped anyone good luck!!!!
Answer:
3.5
Explanation:
Mechanical advantage = force out / force in
MA = 350 N / 100 N
MA = 3.5
No, the correct answer is <span>biomass.</span>
Approximate the instantaneous velocity by computing the average velocity of the car over the interval [1.95, 2.05] (i.e. the interval centered at <em>t</em> = 2 s with length 0.1 s).
By definition, average velocity is given by
<em>v</em> = ∆<em>x</em> / ∆<em>t</em>
So we have
<em>v</em>(2 s) ≈ (<em>x</em>(2.05 s) - <em>x</em>(1.95 s)) / (0.1 s) ≈ 13.94 m/s
5.0j as we know that work is derived as force into displacement so 5*1=5si force will be 5.0j
