Which object has the least amount of kinetic energy? a car driving down a road a soccer ball rolling down a hill a bicycle locked to a bike rack a satellite orbiting earth

A bicycle locked to a bike

Explanation:

The kinetic energy of an object when an object is moving. The mathematical expression for the kinetic energy of an object is given by :

Where

m is the mass of an object

v is the velocity of an object

First option : A car driving down a road, the car is moving i.e. it will possess kinetic energy.

Second option : A soccer ball rolling down a hill, the ball is moving i.e. it will possess kinetic energy

Third option : A bicycle locked to a bike, neither bicycle nor bike is moving i.e. it will not possess kinetic energy.

Fourth option : A satellite orbiting Earth, the satellite is moving i.e. it will possess kinetic energy.

Hence, "a bicycle locked to a bike " has least amount of kinetic energy.

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.
