PLEASE ANSWER
Irina-Kira [14]

Answer:

Farm = 98.1 [N]

Explanation:

To solve this problem we must draw the respective free body diagram, with the forces acting on the monkey. An analysis of the sums on the y-axis must be performed, in this axis the weight is acting down and the forces of both arms pulling up.

Weight is defined as the product of mass by gravitational acceleration.

W = m*g

where:

m = mass = 20 [kg]

g = gravity acceleration = 9.81 [m/s²]

W = 196.2 [N] (units of Newtons)

As this force points down, the force of both arms must go up, therefore each arm exerts a force of:

Farm = 196.2 / 2

Farm = 98.1 [N]

What is the magnitude of the centripetal force that must be applied in order for a 2kg ball on a 2.0 m string to spin with unifo
NeTakaya

The ball needs to accelerate with a magnitude <em>a</em> (pointed towards the center of the circle) of

<em>a</em> = (5.0 m/s)² / (2.0 m) = 12.5 m/s²

Then the required tension <em>F</em> in the string would need to be

<em>F</em> = (2 kg) (12.5 m/s²) = 25 N
