If an 8.7 kg object is moving at a rate of 5.6 m/s on a rope that is 0.5 m, what is the magnitude and direction of the centripetal acceleration

magnified images possible images can be real = projected onto a screen

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.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

c. 127 in.2

d. 1,018 in.2
