1-Using the above “mean-speed theorem”, calculate the average velocity of a car with constant acceleration from 0 km/hour (initial speed) to 90 km/hour (final speed) over a 5 minute period of time. A. average velocity over 5 minutes = 45 kilometers/hour average velocity over 5 minutes = 30 kilometers/hour average velocity over 5 minutes = 18 kilometers/hour average velocity over 5 minutes = 15 kilometers/hour average velocity over 5 minutes = 12 kilometers/hour

According to Isaac Newton, if the distance between Earth and the moon were to triple or increase three-fold (increasing from 240,000 to 720,000 miles), then the gravitational force between them would: increase three-fold from its present value increase nine-fold from its present value remain the same as its present value decrease to one-third of its present value decrease to one-ninth of its present value

a toy car rolls 10 meters (m) across the floor. it takes 5 seconds (s) to cross this distance. what is the speed of this car?

According to Jean Buridan’s equation, the momentum or “impetus” of an 88 kilogram mass moving at 5 meters per second would be: 110 kilogram-meters per second 220 kilogram-meters per second 440 kilogram-meters per second 660 kilogram-meters per second 880 kilogram-meters per second
