Achild on a spinning playground ride is 0.36 m from the center of the ride. the centripetal force on the child is 19 n. what is the mass of the child if the child has a tangential speed of 0.54 m/s? 3.7 kg13 kg23 kg79 kg

Explanation:

As we know that the centripetal force in uniform circular motion is given as

now we have

v = 0.54 m/s

R = 0.36 m

so we will have

choosing tennis and golf balls is your inde choice.

their mass and volume are dep

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
