Well let's see:  Centripetal force = (speed²) / (radius of the circle)

So when there's a centripetal force driving an object in a circular path, the square of the object's speed is directly proportional to the force, and the radius of the circle is inversely proportional to the force.

So this means that . . .

-- if the centripetal force increases, then the object can whiz around a smaller circle at the same speed, and

-- if the centripetal force decreases, then the object will move out to a bigger circle at the same speed.

Here is your answer:

First find the notations:

5.0×10^2=500.
1.0×10^3=1,000

Then you multiply:

1,000×500=500,000

Your answer is...
=500,000 or 5.0×10^4

A person rolls a barrel up an inclined plane with a length of 6m and a height of 3m/ How much force is needed to roll up the bar
snow_lady [41]

Answer:

Length (l) = 6 m

height (h) = 3 m

Load(L) = 500 N

Effort (E) = ?

we know the principal that

E * l = L * h

6 E = 500 * 3

6E = 1500

E = 250

therefore 250 N work is done on the barrel.

The drawing shows Robin Hood (mass = 85.0 kg) about to escape from a dangerous situation. With one hand, he is gripping the rope
mixas84 [53]
The resultant force on the system is equivalent to the difference in the weights of the chandelier and Robin Hood.
F(net) = 240g - 85g
F(net) = 155g

Robin Hood's Acceleration:
F = ma
155g = 85a
a = 17.89 m/s²

Tension = mg + ma
Tension = 85(g + a)
Tension = 2400 N
