12. If an object has a mass of 20 kg, what is the force of gravity acting on it on Earth?
Weegy: If an object has a mass of 20 kg, The force of gravity acting on earth is 196N.
Solution:
force =mass *acc , force = 20 *9.8 = 196N

Weegy: A figure skater skating across ice, who grabs another skater and brings him along the ice with her, is an example of Elastic collision.
User: An object has a momentum of 4,000 kg-m/s and a mass of 115 kg. It crashes into another object that has a mass of 100 kg, and the two objects stick together. If the momentum is conserved, what is the new velocity of the combined object? Round to the nearest hundredth
Weegy: An object has a momentum of 4,000 kg-m/s and a mass of 115 kg. It crashes into another object that has a mass of 100 kg, and the two object stick together. [ If the momentum is conserved, the new velocity of the combined object is: Momentum=mass * velocity; P = m * v; 4000 = 115 * v; v=4000/115 =34.78 ...
