What is the centripetal force that would be required to keep a 4.0 kg mass moving in a horizontal circle with a radius of 0.80 meters at a speed of 6.0 meters/second?

1.8 × 102 newtons radially inward

The centripetal force will be 180 N inward.

Explanation:

Given that,

Mass = 4.0 kg

Radius = 0.80 m

Speed = 6.0 m/s

The centripetal force is define as the mass multiplied by tangential velocity squared, divided by the radius.

The formula of the centripetal force

Where, m = mass

v = velocity

r = distance

We substitute the value into formula

Hence, The centripetal force will be 180 N inward.

0.11 m/s and 0.28 m/s should be correct
