Answer:
C.) The same as one
Explanation:
Because the Ferris wheel has two bars at the side that keep it in place so it doesn't roll away. The Ferris wheel only moves in one place. If the ferris wheel did roll then you would have a greater than one. If it did roll it would be dangerous.
Presumably, the ball is kicked parallel to the ground below the cliff, so its altitude <em>y</em> at time <em>t</em> is
where <em>g</em> = 9.80 m/s^2 is the acceleration due to gravity.
The ball hits the ground when <em>y</em> = 0:
Explanation:
hmm by the increasing the size of wheel and decreasing axle
Heaviest one always have the most kinetic E. for example, Didier drogba was running then nobody can stop him cuz his heavyyyyyy
Hannah comes to a rest in <em>t</em> = 0.4 s, so her acceleration is
<em>a</em> = (0 - 25 m/s) / (0.4 s) = -62.5 m/s²
(that is, the acceleration points in the direction opposing her movement forward as she brakes)
Then the force exerted on her by the seatbelt has magnitude
<em>F</em> = (65 kg) (62.5 m/s²) = 4062.5 N ≈ 4063 N
