Answer:position relative to the starting point
Explanation:
<h2>Answer</h2>
Radius is 421 m.
<u>Explanation </u>
A car with a mass of 1,500 kg requires a centripetal force of 640 N to safely follow a circular curve in the road at 13.4 m/s. Therefore, for radius we use formula which is Fc = mv ^ 2 / r,
As mass = m = 1500kg,
Centripetal force = Fc = 640N,
Velocity = v = 13.4 m / s
By putting values, Fc = mv ^ 2 / r,
r = mv ^ 2 / Fc,
=> r = ( 1500kg ) . ( 13.4 m / s) ^ 2 / 640,
=> r = ( 1500kg ) . ( 179.56 ) / 640,
r = 269340 / 640,
=> r = 420.84 m.
Radius is 421 m.
The correct answer is a blackhole.
A blackhole is the only object in which nothing, not even light can escape.
Hope this helps!
Independent, and inverse means if one variable increases then the other decreases, direct is when they both go up or down together.
