A3.8 kg cat is standing on a rotating platform of radius of 1.5 m from the center of the platform. then the operator turns on the ride and brings it up to a rotating rate of one revolution every 4.0 s a) identify the net force on the cat b) calculate the net force acting on the cat c) the cat begins to walk radially outward. he realizes that he begins to slide when he reaches a radius of 2.7 m. assuming the same rotation rate, calculate the of static friction between the cat and the rotating platform.

(b). The net force is 14.06 N.

(c). The static friction is 0.68.

Explanation:

Given that,

Mass of cat = 3.8 kg

Radius = 1.5 m

Time = 4.0 sec

(a). We need to Identify the net force on the cat

We draw the figure for identify the net force on the cat

The net force on cat is

(b). We need to calculate the net force acting on the cat

Using formula of centripetal force

Put the value into the formula

(c). We need to calculate the static friction between the cat and the rotating platform.

Using relation of frictional formula and net force

Put the value into the formula

Hence, (b). The net force is 14.06 N.

(c). The static friction is 0.68.

the force on the thing and the distance the force moves the thing

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
