Weegy: The acceleration of gravity is a constant equal to 9.8 meters per second squared.
User: The Ptolemaic model of the universe describes the earth as
Weegy: The Ptolemaic model of the universe describes the Earth as Earth-centered or geocentric.
User: If a man has a mass of 83 kilograms on earth, what will the force of gravity on his body be on the moon
Weegy: If a man has a mass of 83 kilograms on Earth, the force of gravity on his body be on the moon 135.6 N.
force =mass*acc , 83 * 9.8/6= 813.4/6 = 135.6N
User: A person with s mass of 15 kg is walking uphill at a velocity of 2 m/s. What is the walkers momentum
Weegy: A person with a mass of 15 kg is walking uphill at a velocity of 2 m/s. 30 kg m/s is the walkers momentum.
Put m= 15 kg and v= 2 m/s
p=(15)(2)
p= 30 kg m/s
User: A remote-controlled car travels at a uniform speed of 3.5 m/s and reached its destination in 5 minutes. How fr did the remote-controlled car travel
Weegy: A remote-controlled car travels at a uniform speed of 3.5 m/s and reaches its destination in 5 minutes. 1050 meter the remote-controlled car travel.
Solution:
Speed = Distance/time , 5 min = 5*60 sec. [ 3.5 = distance /5 *60 , distance = 3.5*5*60 = 1050 meter . ]
User: A person with a mass of 15 kg is walking on a flat surface at a velocity of 5 m/s. What’s the walkers moments
Weegy: A person with a mass of 15 kg is walking on a flat surface at a velocity of 5 m/s. The walkers momentum is 75 kg m/s.
p = mv
15 kg * 5 m/s = 75 kg m/s
User: The model of the universe that suggest that the sun is in the center of the universe was first developed by
Weegy: The model of the universe that suggests that the Sun is the center of the universe was first developed by: Copernicus.
User: A 5000 kg train is traveling at a velocity of 100 m/s and hits another train. The two trains stick together, and the new velocity is 50 m/s. What is the mass of the second train
Weegy: 5,000 kg train is traveling at a velocity of 100 ...
